History Main / KissingUnderTheInfluence

** In an early episode, Ranma's [[UnstoppableRage "Cat-fu"]] is revealed to be calmed by laying on Akane's lap, purring like a cat. The first time this happens he gives her a little kiss on the cheek (acting like an affectionate cat). Embarrassed, she gives him the MegatonPunch.

* In the ''Series/StarTrekTheNextGeneration'' episode "The Naked Now", Data and Lt. Tasha Yar have sex while under the influence of the same alcoholic intoxication disease that inflicted the TOS crew in "The Naked Time." After they were cured, Tasha told Data that the whole thing never happened.

* In the first season of ''Series/SchittsCreek'' David and Stevie get stoned and giggly, and to her surprise, he kisses her. The next episode begins with the couple awkwardly naked beneath the motel's red satin honeymoon sheets and regretting what has happened. This leads to David coming out as [[BiTheWay pansexual]] and a brief FriendsWithBenefits relationship before the pair settles into becoming [[BetterAsFriends best friends]] and AmicableExes.

* Happened in an episode of ''WesternAnimation/JimmyNeutron'' where everyone fell absurdly in love with the first thing they saw.

* In the Literature/CiaphasCain series (specifically ''For The Emperor'' and the short story "Sector 13"), Tyranid Genestealers are implied to force this upon their victims. Genestealers spread TheVirus to create "cults" of apparently loyal humans who will turn to the Tyranid side as soon as the hive fleet arrives in the system (or whenever would best suit their needs). To do so, they abduct and attack humans, then implant them with an organelle that lodges in their chest cavity. The main function of the organelle is to gradually infect the victims' children, who are also born with Genestealer implants. As the generations pass, mutations grow more extreme until eventually, they birth a combination of nearly-normal humans (for infiltration) and Genestealer Purestrains, which are vicious close-combat specialists that protect the cult and look nothing like humans. To ensure the hosts ''have'' children, the implants subtly encourage them to form attachments and have sex at every opportunity, especially (but not necessarily) with other hybrids.

** Once, after being snagged by a Fishing Rod of Love, Ranma fell under a spell that made him fall in love with [[TheRival Ryoga]]. As a girl, Ranma would then kiss him lovingly on the cheek -- Ryoga's [[{{Squick}} reaction]] was [[UnstoppableRage less than pretty]].

[[folder:Film]]

* Happens to [[spoiler: Brent and Tanner]] in ''{{Film/GBF}}'' (and maybe [[Main/DidTheyOrDidntThey something else]])

* In ''Film/Venom2018'', [[spoiler:Anne Weying (using the Venom symbiote) kisses Eddie Brock, thus transferring the symbiote back to him]]. It had been set up earlier in the film that [[spoiler:Venom was pushing Eddie to make amends with her, and it's implied that it forced Anne to kiss him. However, at the end of the film, there is noticeable insecurity in her words when she says the symbiote made her do it, and she says she won't tell her boyfriend about it]].

* ''Series/{{My Babysitters a Vampire}}'': Erica kisses Benny while under the effects of Benny's {{Love Potion}}. Benny is more than excited about this.
-->'''Benny:''' I...kissed...Erica!

* ''Series/{{Scrubs}}'' had a kiss between J.D. and Carla in season 4. Both were drunk and the morning after exchange was hilarious:
--> '''JD:''' It was a friend kiss, and we'll never talk about it to anyone ever!\\

'''JD:''' Nothing!\\
'''Carla:''' JD and I kissed!\\
'''JD:''' Carla!\\

'''JD:''' Yes...\\

'''JD:''' CARLA! YOU'RE KILLING ME!

-->'''Naomi:''' ''[Motioning between the bottles in her hand]'' So, what do you want?\\

* [[Webcomic/{{Achewood}} Man, chicks will do anything on Cuervo! They'll even lez out!]]

[[folder:Web Original]]

* A variation in ''Fanfic/YouCallThatACostume'': while transformed into [[FurAgainstFangs a vampire bat and werewolf]] due to a BecomingTheCostume spell, Fluttershy and Rainbow Dash act like a pair of mating animals. Upon returning to normal, they do a TestKiss to see if it actually meant anything. They end up becoming a couple.

* A variation in ''Fanfic/YouCallThatACostume'': while transformed into [[FurVersusFangs a vampire bat and werewolf]] due to a BecomingTheCostume spell, Fluttershy and Rainbow Dash act like a pair of mating animals. Upon returning to normal, they do a TestKiss to see if it actually meant anything. They end up becoming a couple.

* In ''Film/WhenEvilCalls'', a boy with a crush on Molly wishes that he could kiss her. Under the influence of the wish, Molly kisses him; very enthusiastically.However, the boy had not counted on Molly's [[ClingyJealousGirl psycho girlfriend]].

* In ''Series/DoctorWho'', Rose, while possessed by Cassandra, kissed the Doctor. His response: "Yep. Still got it." (In a very squeaky voice with eyes glazed-over).

Two characters kiss due to the influence of mind-altering AppliedPhlebotinum -- or just plain ol' mind-altering substances like alcohol -- to which one (or possibly both) of them have been exposed. The kiss may be directly caused by scientific or magical means, or be the eventual result from some kind of [[LovePotion love spell]]. In one-sided cases, even though the unaffected participant is hardly if ever the one who cast the spell, he or she doesn't object.

This affliction usually strikes characters (a) who would never kiss when they're both sane, (b) whom fans have been dying to see kiss for many a season, or both. The trope's potential lies in the fact that the couple's {{shipp|ing}}ers can {{Squee}}, and everyone else can brush it off with, "[[ItDoesntMeanAnything It wasn't real]]."

* ''Manga/{{Moyashimon}}'' has the unforgetable episode where Hazuki Oikawa and Aoi Muto take aphrodisiacs. They think it has no effect on them... But their thoughts might be different [[BedmateReveal the following morning]]. Sado-Masochist Hasegawa has a somewhat different reaction (though admittedly she [[InVinoVeritas also had alcohol]], as did the other two in the manga).

* ''Fanfic/{{HERZ}}'': In the backstory Kurumi kissed Shinji when he was heavily inhebriated [[spoiler:and then the got her way with him.]] She hoped that action led to they becoming a couple, but it backfired horribly: Shinji kept loving Asuka and he was so ashamed of what happened he started to actively avoid Kurumi.

* In ''Fanfic/TheStudentPrince'', Gwen and Arthur kisses each other at a party while they are both drunk out of their minds, although nothing comes of it.

* In the ''Fanfic/EmpathTheLuckiestSmurf'' story "My Unsmurfy Valentine", Eros' lust arrows strike various male Smurfs who start kissing each other. Only it doesn't affect Tapper because he has some sort of [[ReligionIsMagic spiritual protection]]. In "Monkey On Your Smurf", Empath and Smurfette are under the influence of probes inside their bodies that are making them make out with each other. And of course there's Papa Smurf in [[HulkingOut Hulked Out]] mode seeking to mate with Smurfette in "Papa's Big Crush."

-->Suddenly, Scott was caught in Jean's eyes like a net. His mouth met hers and Jean responded back. Their tongues and minds entwined, and Scott found himself running his hands though her wild red hair. Jean's hands were all over him. The next thing Scott knew, they were on the ground with Jean on top of him. She looked like some pagan goddess, looking down at him with passion-bruised lips and her hair all mussed.

* In Creator/LinneaSinclair's ''Gabriel's Ghost'', Sully self-medicates his mental problems with [[FantasticDrug honeylace]]. While [[strike:drunk]] furred on liquid courage he works up the nerve to kiss his long time crush. She goes along with it at first, but eventually breaks away because [[AboveTheInfluence she thinks he'll regret it in the morning.]]

* ''Literature/ArtemisFowl'', [[spoiler: Holly kisses Artemis when they go into the past, because the magic that transported them there turned her into a teenager and messed up her hormones.]] Makes certain events in the next book hilarious.
* In the Literature/CiaphasCain series (specifically ''For The Emperor'' and the short story "Sector 13"), Tyranid Genestealers are implied to force this upon their victims. Genestealers spread TheVirus to create "cults" of apparently loyal humans who will turn to the Tyranid side as soon as the hive fleet arrives in the system (or whenever would best suit their needs). To do so, they abduct and attack humans, then implant them with an organelle that lodges in their chest cavity. The main function of the organelle is to gradually infect the victims' children, who are also born with Genestealer implants. As the generations pass, mutations grow more extreme until eventually they birth a combination of nearly-normal humans (for infiltration) and Genestealer Purestrains, which are vicious close-combat specialists that protect the cult and look nothing like humans. To ensure the hosts ''have'' children, the implants subtly encourage them to form attachments and have sex at every opportunity, especially (but not necessarily) with other hybrids.

** The sequel series ''Literature/TheInfernalDevices'' shows that too. Will and Tessa both drink something that is enriched with witch's powder, and become almost intimate with each other. However, Magnus Bane comes just in time to stop her.

** In a later episode B'Elanna and Tom hook up for real and start MakingLoveInAllTheWrongPlaces, earning a formal reprimand from the captain. In that episode aliens are discovered doing secret medical experiments on the crew, and they wonder if their sex-mad behaviour, perhaps even their entire relationship, might be a result of some aliens messing with their hormones as an experiment. Well, it's a good thing they found out in time, Tom and B'Elanna conclude [[HypocriticalHumor while snogging passionately]].

* ''Series/StargateAtlantis'', where in one episode Rodney and a female soldier share Rodney's body between them. First she advances Rodney's social life by taking control of his body and kissing the woman he has a crush on. Then, at the end of the episode, she takes control again, but this time to kiss the ''man'' that ''she'' has a crush on, before undergoing the [[AppliedPhlebotinum risky reversal procedure]]. This last caused squee overload for slash fans because onscreen it's just two guys kissing.

** Subverted when Ethan and Sarah almost kissed after being transformed into ''Series/{{Dusk}}'' lovers, but returned to normal at the last second putting them in an awkard situation.

** "Band Candy": Under the influence of a spell that makes adults act like teenagers, Giles and Joyce listen to sixties music, smoke, rob a store, and oh yeah, have sex (though the last isn't confirmed for several more episodes). They're awkward around each other afterwards and apparently eventually decide ThatDidntHappen; [[spoiler:however, apparently the memory was a fond one for Giles, because when Joyce dies he can be seen mournfully listening to the same records.]]

** "Once More With Feeling": A second case of Buffy and Spike KissingUnderTheInfluence... sort of. (Subverted when, a couple episodes later, [[spoiler:they begin a sexual relationship]].)

* In the ''Series/{{Farscape}}'' episode "Meltdown," Crichton and Aeryn are affected by fluids from Talyn that make them consumed with mutual lust. In one amusing scene they have to snog, frantically complete some essential repairs, then gratefully go back to snogging again (this example is actually playing with the concept, as John and Aeryn were ''already'' in an intimate relationship during this episode. Talyn's fluids just ramped them up into overdrive). Likewise an alien infiltrator increases everyone's emotions prior to draining them in "Twice Shy". Chiana's already considerable sex drive is increased, leading to her [[strike:almost]] kissing the (female) alien, cornering and attempting to flirt with Aeryn, and trying to forcefully 'recreate' with John Crichton on a table.

* In ''Series/{{Glee}}'', Blaine (who is gay) and Rachel kiss while they are both playing a drunken game of spin the bottle. They both think there might have been something there, until Rachel kisses him again while sober. There wasn't.

'''Emily:''' ''[Completely mesmerized by her]'' Anything. Just give me a fucking... Just.. Just give me a... ''[leans over and kisses her. Naomi shows absolutely no resistance]''\\

* On ''Series/TheOrville'', this becomes the plot of the episode "Cupid's Dagger" courtesy of a visiting alien's pheromones. It also comes close to completely ruining a delicate bit of negotiations, almost leading to a full-scale war.

* In the first season of ''Series/SchittsCreek'' David and Stevie get stoned and giggly, and to her surprise, he kisses her. The next episode begins with the couple awkwardly naked beneath the motel's red satin honeymoon sheets and regretting what has happened. This leads to David coming out as [[BiTheWay pansexual]] and a brief FriendsWithBenefits relationship before the pair settles into becoming [[BestFriend best friends]] and AmicableExes.

** This trope is applicable in an update wherein an intoxicated Rose kisses Kanaya. Cue fandom flipout. However, it seems that they had basically been going out for a while beforehand, so it wasn't out of nowhere.

** Timmy uses TheDarkSide suit for this purpose on Trixie in "The End of the Universe-ity". He also tries in "Genie, Meanie, Miney, Moe", but it's though [[JackassGenie Norm]]. "You Doo" is a debatable example, while the dolls could control actions, there was no evidence it could change personality. A variation occurs in "Love Struck!", when Timmy puts a spell on himself so he can date Tootie.

* In an episode of ''WesternAnimation/JonnyQuestTheRealAdventures'' Jonny and Jessie get possessed by the ghosts of two lovers who murdered each other over a jealous spat. Hadji and another character convince the spirits to literally kiss and make up... [[https://www.youtube.com/watch?v=WXix3MHTx-Q&feature=related while still in Jonny and Jessie's bodies]]. There's a brief awkward moment between the two after (the fact that they failed to notice the ghosts had left them for several seconds probably didn't help), but is passes fairly quickly. Jessie even teases Jonny about it later in the episode.

* ''Series/StargateSG1'': Sam kisses Jack in "Broca Divide" after turning into a cavewoman; every male character who kisses Hathor is under the influence of her weird breath. It happens more than just these times...

* The "alien orgasm monster" from the ''Series/{{Torchwood}}'' episode "Day One".
* In the ''Series/{{Farscape}}'' episode "Meltdown", Crichton and Aeryn are affected by fluids from Talyn that make them consumed with mutual lust. In one amusing scene they have to snog, frantically complete some essential repairs, then gratefully go back to snogging again (this example is actually playing with the concept, as John and Aeryn were ''already'' in an intimate relationship during this episode. Talyn's fluids just ramped them up into overdrive). Likewise an alien infiltrator increases everyone's emotions prior to draining them in "Twice Shy". Chiana's already considerable sex drive is increased, leading to her [[strike:almost]] kissing the (female) alien, cornering and attempting to flirt with Aeryn, and trying to forcefully 'recreate' with John Crichton on a table.

* Thanks to Morgana's evil plan, Gwen kisses Lancelot under the influence of a magic bracelet in season 4 of ''Series/{{Merlin}}''.

* ''Series/StargateSG1'': Sam kisses Jack in "Broca Divide" after turning into a cavewoman; every male character who kisses Hathor is under the influence of her weird breath. It happens more than just these times...

* In ''Series/{{Smallville}}'' fanfiction "[[http://archiveofourown.org/works/848400/chapters/1621084 Under The Influence]]", [[Franchise/{{Superman}} Clark]] and [[Comicbook/{{Supergirl}} Kara]] kiss while they are under the mind-altering influence of red kryptonite.

* The plot of ''[[Literature/MixBeerWithLiquorAndYouWillGetSicker]]'' is set off this way, as protagonist Lauchlan Huxley awakes after having a few drinks too many in a stranger's bed - a male stranger over that.

* In ''Film/MazeRunnerTheScorchTrials'', Thomas and Brenda make out at a post-apocalyptic rave party after they've been imbibed with hallucinogenic drugs. This also causes Thomas to image Teresa in her place, whom he's really in love with.
