YouTube Poop, often shortened to YTP, emerged on YouTube in the mid 2000s as a form of video remix that cut up cartoons, adverts and game cutscenes into repetitive, surreal jokes. Early creators reused recognisable intros, titles and stingers so viewers knew immediately they were watching a poop rather than the original source. This intro clip circulated as part of that shared template culture and survived through reuploads and meme compilations, remaining a shorthand for early YouTube remix humour long after the format peaked.
