Super Smash Bros Ultimate, released for Nintendo Switch in 2018, uses this sound when a fighter is knocked out and loses a stock during a match. As clips from the game spread on YouTube, TikTok and Twitch, editors began lifting the short knockout sting for their own fails, eliminations and reaction videos. Like the Roblox oof sound, it has become shorthand online for sudden defeat, because listeners recognise it instantly even outside Smash. Its brevity and clear finality keep it useful for short-form edits years after release.
About this sound
Super Smash Bros Ultimate death sound effect, heard when a fighter is knocked out of a match. Popular for fail clips, eliminations and game over edits.
This is the short sound that plays in Super Smash Bros Ultimate when a fighter is knocked out and loses a stock. It starts with a sharp impact, then drops into a fast, downward swoosh as the character is launched off the stage, before cutting out abruptly. That sudden drop and silence make the defeat feel final and a little comic at the same time, which is why it lands so well outside the game too. Listeners instantly recognise the moment of failure, even without seeing the screen, and the clip is short enough to punch up a joke without slowing an edit down.
