Pikachu has been a playable fighter since the first Super Smash Bros, but this clip comes from Super Smash Bros Ultimate, the Nintendo Switch fighting game released in 2018. In matches, a fighter is knocked out when launched past the stage boundaries, triggering a distinctive cry and launch effect. Clips of those moments spread through gameplay videos, streams and short-form edits, where the sound became shorthand for a sudden, decisive defeat. It remains popular because it is instantly recognisable to Smash players and works even for viewers who have never played the game.
