YouTube Poop, often abbreviated as YTP, is a type of video mashup, created by editing preexisting media sources (usually in Sony Vegas) for humorous, confusing or shocking purposes and often containing mature content. YouTube Poop videos are traditionally uploaded to the video-sharing website YouTube, hence the name, but may be mirrored or uploaded on other video sharing websites like Newgrounds, VidMe, and/or Dailymotion.
In a typical YouTube Poop video, visual and auditory effects are used to alter the underlying work. Some of these videos may involve completely or partially repurposing sources to create or convey a story, while others follow a non-linear narrative. Some contain no storyline at all. Alternatively, a YouTube Poop may consist solely of an existing video repeated in a slowed or remixed loop. In many cases, YouTube Poops utilize a bizarre sequence of elements that may entertain, confuse or irritate, depending on the viewer. Associate professor of cultural anthropology at Kansas State University Michael Wesch has defined YouTube Poops as "absurdist remixes that ape and mock the lowest technical and aesthetic standards of remix culture to comment on remix culture itself".
Media sources of YouTube Poops may include television shows, movies, cartoons, commercials, video games, and other videos obtained from YouTube or elsewhere. There is no generally accepted limitation as to what kind of source material may be used for a YouTube Poop. Some primary sources include cutscenes from Zelda: The Wand of Gamelon, Link: The Faces of Evil, Hotel Mario and I.M. Meen as well as SpongeBob SquarePants, King of the Hill and works featuring Michael Rosen, Billy Mays and Dr. Rabbit. YouTube: Online Video and Participatory Culture notes YouTube Poop having a particular fascination with "low" Saturday-morning American cartoons from the 1990s such as The Super Mario Bros. Super Show!, Adventures of Sonic the Hedgehog and Mega Man as well as anime series, video game cutscenes and videos from YouTube itself.
