YouTube Poop, shortened to YTP, emerged on YouTube in the mid 2000s as a form of video remix where film and television clips were re-edited with repetition, sentence mixing and visual gags. Harry Potter became a frequent source because its dramatic lines and well known characters were instantly recognisable, making distorted versions funnier. Clips circulated through early meme culture and later short form reposts, and this style of meme edit remains popular because a few seconds of scrambled dialogue can signal an entire era of internet humour without needing any setup.
