The sound comes from Super Mario Bros, released by Nintendo in 1985, where it plays whenever Mario loses a life. Composed as part of Koji Kondo's original soundtrack, the short descending tune became inseparable from the feeling of failing in a Mario game. As gameplay clips, speedruns and reaction videos spread online, creators began lifting the jingle out of its original context to mark any kind of failure. Its instant recognition across generations of players keeps it in constant use in memes, streams and short-form videos today.
