The tune comes from Nintendo's Mario Bros arcade game, where it played when a player ran out of lives and the game ended. As Mario moved from arcades to home consoles and later games, the short melody stayed closely associated with losing, making it easy for viewers to recognise even without seeing the gameplay. Online creators later adopted it as shorthand for failure, using it over clips of mistakes, defeats and bad luck, and that simple, instantly understood meaning has kept it in regular use decades after its arcade debut.
