Suicide Mouse, or suicidemouse.avi, is one of the internet's oldest and most notorious creepypastas, purportedly showing a lost 1930s Mickey Mouse cartoon. The footage features a despondent Mickey walking past a looping background while dissonant piano music transforms into agonizing screams and static. While the video was a digital creation rather than a genuine Disney relic, it sparked a massive wave of urban legends and fan-made variations. In meme culture, it is often used to represent overwhelming existential despair, deep sadness, or a transition into a dark, cursed state of mind, typically characterized by its grainy, black-and-white aesthetic.
