If you're bored one night with nothing to do but watch YouTube, and don't mind waking up with a crippling hangover, take a drink whenever you encounter:
- Epic Fail videos, which mainly consist of someone trying and failing to pull off a stunt.
- Snarky blogs by online users.
- The latest trailer for a major movie release, usually copied off a website, or as the service has become more popular, released directly by the studios.
- Cat videos.
- Durability tests wherein an electronic device is either smashed with a sledgehammer, lit on fire, or shot with a gun.
- Several videos from a recently-held sporting event (bonus points if it involves a ridiculously improbable shot or goal).
- Political commentary videos.
- Videos promoting conspiracy theories, usually something along the lines of a musician being a member of The Illuminati.
- Parts of the latest episode of America's Next Top Model.
- American Idol/Britain's Got Talent performances.
- A spam filter for the comments section.
- A video that's been marked as age-restricted despite the content being similar to non-restricted videos.
- A video that had its audio removed due to one of its music tracks not being authorized by a major record label.
- A video removed for terms of use violation (most times for obvious reasons, though other times, it's anyone's guess why).
- A video getting removed for copyright infringement.
- A video getting removed because the YouTube account associated with that video is deleted (for example the account was banned due to Multiple or Severe Community Guideline Violations, Multiple or Severe Copyright Violations, or they just closed their account).

- Videos of people doing everyday, ordinary things, or just playing around.
- Videos complaining about YouTube censorship.
- Screamers and Jump Scares in general(protip).
- The occasional Rickroll.
- YouTube Poop. If you really want to get smashed, it has its own drinking game within.
- Video game Lets Plays and walkthroughs.
- A video of someone taking something out of a box.
- A prank that's not related to Screamers.
- Videos with millions of views about people talking about absolutely anything while playing video games.
- Videos that begin with a montage of parts of games put to a song as an intro.
- Videos that end by asking the viewer to subscribe to the channel.
- Videos that begin by asking the viewer to subscribe to the channel. Before the video shows what people would subscribe for.

- Don't forget the hate videos that popped right the fuck out of nowhere in 2011 and were forgotten as if they never happened.
- Episodes of still-running or forgotten TV shows. Some users will trick people into viewing their video by uploading a spoof image of an expected episode and filling it with spam, a still image, or a link to their own site instead. However, a portion of the site is dedicated to officially uploaded full seasons/series for shows ranging in age from the '60s to the late '00s. Not outside the US (and sometimes Canada and/or the UK).
- Fanimes / fanvids.
- Flash animation videos from sites like Newgrounds or Nico Nico Douga.
- Funny captions that are (for the most part) way, way off from what's being spoken.

- Similarly, videos of Guitar Hero and Rock Band charts and full screen (with the person playing not recording them dancing) "Just Dance" routines .
- Minecraft videos.
- Old movies in multiple parts or in one long video. These will either be public domain, or so old/obscure the current copyright holder either doesn't know or doesn't care that it's up on Youtube. Still best to watch them quick in case they do decide to take it down.
- Take another drink when you luck out and it was the copyright holder themselves that uploaded the film or show, perhaps hoping to make money off ad revenue because it's so obscure they can't profit from it any other way.
- Parodies of almost any popular song you can imagine.
- Popular scenes and moments from movies, TV shows, and the like.
- A song, particularly a music video, played backwards (or if the lyrics don't match the video's visuals, a "literal music video").

- Videos of people doing really stupid things.
- Reaction videos, either of something very nasty, or popular TV shows. Yes, there is an entire YouTube genre of watching people watch TV.

- Videos labeled "Bloopers" that turn out to be fanmade bloopers.
- Videos redirecting you to a website saying that you can watch the video there - that will force you to make an account, take a survey, never allow you to watch the video, and send you spam.
- Videos that have virus links. There's always one up. Most notably the spam you've been seeing on your Facebook profile, disguised as a link to something "shocking!". Either that, or it's a video saying it's the full movie of a film still in theaters when it's really just a screencap or at most a trailer, with virus links in the description.
- Videos of kids throwing temper tantrums when asked to go off the computer and leave their online games.
- Short video clips of rage scenes (Such as Penn Jillette's YOU NEED TO SHUT THE (BLEEP) UP!

- Caramelldansen Vids

- News channels that may or may not be of dubious veracity or authenticity—and are not even satirical news shows similar to The Daily Show. These channels would also have clickbait-y headlines and videos that are copied (usually without permission) from legitimate television news outlets while passing themselves off as a legit news channel.
- Amateur DIY videos revealing the "secret trick" to taking the radio out of an '88 Dodge or repacking the CV joints on a 2003 Honda with titles like "taking the [thingamabob] out of your [whatsit]".
- Self-proclaimed "booty shaking" videos. Miley Cyrus might have made "twerk" a household word in 2013, but the phenomenon got started on YouTube long before the term itself was in common parlance.
- Vine Compilations. Usually of all the above.
- Fetish porn, which gets around Youtube's policies by not showing sex or nudity. This includes official previews from professional sites, pirated full videos from said sites (until they're taken down), and amateur videos. Note this also means that completely innocuous videos that happen to be "useful" are also shared among fetish communities. That funny video of your ticklish friend laughing through a pedicure? Someone's masturbating to it as we speak.
- Lots and lots of Top 10 Lists, most likely by WatchMojo or one of their imitators.
- Good old fashioned Paint Drying.

- Animated videos where the narrator talks about their life or opinions. These YouTubers are sometimes said to be part of "the animation squad".
- Sponsor segments... but only the ones that essentially tell viewers to enter the same code twice. There's already too much of the regular kind.
- Loudwire countdowns of metal + rock moments. In addition, go into the comments for one of these videos and take a drink for every comment bashing pop music or any comment along the lines of "[metal singer]: [does something along the lines of The Show Must Go On in the face of an onstage mishap, often risking their health & safety in the process]; [pop singer]: [ends the show for their own health & safety]" (screw it, the ambulance can't save you).
- Removal of features for no good reason, despite community backlash.
- YouTube's incredibly senile and troll-like abuse of content makers and viewers.
- COPPA, whether something got marked for kids, often incorrectly, or there's a disclaimer that the video/channel is not intended solely for kids.
- A YouTube critic makes a video about how The Lord of the Rings: The Rings of Power is an insult to Tolkien.
- A negative review of whatever animated product everyone is picking on which features at least one of the subsequent things:
- Either the title or the thumbnail contains a word like "trash", "disaster" or "pathetic"
- The thumbnail contains the Rotten Tomatoes rating, in case someone thought this is actually a good product and the reviewer is exaggerating.
- The thumbnail makes the main character look stupid by either picking the least flattering frame or editing the picture to make them wall-eyed.
- The thumbnail has the reviewer's cartoon avatar facepalming or making some other distressed face.
- Railfanning videos which involve the uploader filming trains of any kind. Take a double shot if it's a foamer gushing about said train's paint job or type of horn.
- An inappropriate child-oriented video from a YouTube Kids' Channel. Down the whole bottle if it's part of the recent resurgence.
- A GoAnimate grounded/punishment day/dead meat video. Take a double shot if it involves Caillou or Dora the Explorer. Down the whole bottle if the parents punish the child for an absurdly long time.
- Roller-coaster POV videos. Take a double shot if the theme park employees catch onto the uploader for breaking the "no phones" rule.
- If you encounter the Offline error on the mobile app, down your glass due to its nature.
