The Brief: "YouTube poop" is a genre of YouTube parody video of bizarrely remixed and edited scenes from classic movies, TV shows, and pop culture moments.
Sometimes abbreviated as “YTP,” YouTube poop refers to a specific style of video that has been heavily edited with random effects. These videos usually consist of some kind of mashup of relatively popular clips, often with edits that make it so people say inappropriate and NSFW things. Reminiscent of video Mad Libs or the movie Airplane! but more chaotic, YouTube poop videos may be shared as memes or inside jokes. Those new to the genre may be left bewildered, wondering “what did I just watch?”
A subreddit: r/ytp dedicated to the sharing of these videos has 6,900 members.
