YouTube Poop, or YTP, is a foundational genre of internet subculture that involves remixing existing media into surreal, nonsensical, and often absurdist videos. Emerging in the mid-2000s, YTP creators utilized video editing software to 'poop' on source material like the Legend of Zelda CD-i games, Adventures of Sonic the Hedgehog, and various commercials. The humor relies on techniques like sentence mixing, where syllables are rearranged to form new, often crude sentences, and 'stutter loops' for comedic timing. Central figures like King Harkinian, Morshu, and Dr. Robotnik became legendary icons of this movement. Beyond just humor, YTP served as a precursor to modern glitch art and the frantic, high-energy editing styles found in contemporary social media content, marking a pivotal era in digital creativity.
