* In the early JimCarrey movie ''Film/OnceBitten'', a coffin is shown rocking to show that the hero's girlfriend is finally doing the one thing that would end their [[VirginSacrifice current problem]]...

* In episode 8x11 of ''{{Series/Supernatural}}'', "LARP and The Real Girl", as quoted above, though Charlie and Gild were only making out. Also Tara's trailer at the end 2x18, Hollywood Babylon.

* Subverted in ''MamasFamily''. In the episode "There Is Nothing Like the Dames", Thelma is trying to impress a small group of snooty upper-class women with a backyard dinner so they will let her join them. Unfortunately, Vinton and Naomi's trailer sits in the driveway, an obvious eyesore. On top of that, during one scene, the trailer starts rocking, horrifying the women... until Thelma finds out that Vinton was only trying to fix a broken table leg.
* Has happened several times on ''MyNameIsEarl'', such as Earl bringing in [[TheIngenue young Amish women]] to "show them a good time," and when Joy was cheating with Darnell.
* ''PushingDaisies'': In the second episode, there's a flashback of the VictimOfTheWeek, a car safety tester, meeting his girlfriend, a promotional model for the same car company. This is followed by the display car in the showroom rocking back and forth, with the windows steamed up. Bonus points for the car being on a turntable.

* ''That70sShow'': Kelso: "If this van's a-rockin, [[SubvertedRhymeEveryOccasion we're inside doin' it]]!"

* ''{{Community}}'' references this as Troy and Abed show new roommate Annie through the apartment - at their bedroom Abed plays with HoYay saying "If the room's a-rocking please come a-knocking because there's probably something terribly wrong."

* A van is rocked this way in the ''MST3K'' feature ''Film/{{Hobgoblins}}'', much to the hosts' disgust.

* ''Salome's Last Dance'' (1988). As Theatre/{{Salome}} starts her famous dance, the woman playing Herodias jumps into a crate with a beefy stagehand. Another stagehand sits on top, trying in vain to have a cup of wine while the crate is jumping up and down. Eventually the lid opens and a finger beckons him [[HammerSpace inside as well]]. As Salome's dance works to its peak, we briefly cut to the crate shaking wildly from the action inside.

* ''{{Titanic}}'': In a car that's on a ship.

** A helicopter being piloted by Barney also does this in midair when the woman he's flying decides to give him some PitySex.

* On ''{{WesternAnimation/Futurama}}'' when Fry and Amy's car gets stranded on Mercury and the two of them decide to "pass the time" and by the time the tow truck arrives the windows are fogged up. Clearly expecting to see some hanky panky going on the tow truck driver wipes away the steam on the window only to find the two of them playing cards. Double subverted when, as they're being towed away, Fry and Amy decide to start making out anyway.

* Subverted (though not in [[DoesThisRemindYouOfAnything the usual way]]) in ''QuestionableContent''.

* Subverted in ''ItsWalky'' when Walky and Joyce try to convince Joyce's [[IWantGrandkids grandchild-obsessed mother]] that they are having sex: the two of them simply [[http://www.itswalky.com/d/20030326.html bounce on the bed loudly like the overgrown kids they are]].

* [[PennyArcade Tycho Brahe]]: Mr. Coulton? Um I know the trailer is rocking, and I really shouldn't knock in this instance, but... they need you for sound check. They want to check your sound.

* [[http://www.youtube.com/watch?v=hD40PU9650s This]] Guinness commercial has a [[AllWomenAreLustful lucky woman having a foursome]] with three guys.

A form of SexyDiscretionShot where a vehicle or other small enclosed space is shown moving vigorously to show that its occupants are "moving vigorously" too. (A common subversion is to then show that the vigorous activity in question [[InnocentInnuendo was not the one you were thinking of]].)

...when this van's a rockin'!
