The sound comes from Mario's in-game falling voice clip in Super Mario 64, the 1996 Nintendo 64 platformer that helped define 3D gaming. Over time, players pulled short character sounds like this into compilations, remixes, and fail edits. It remains popular because the scream is instantly readable even without context: you hear it and expect a bad landing. Online, it fills a similar role to the roblox oof, giving funny failures a fast, game-like punch.
