Super Smash Bros. Ultimate was released by Nintendo in 2018 as the fifth entry in the crossover fighting series, bringing together fighters from many different game franchises on one roster. The blast zone system has been central to the series since the original 1999 game, replacing traditional health bars with percentage based knockback. This fallout effect marks the moment that knockback finally sends a fighter too far to recover. Clips and edits from tournaments and casual matches helped the sound spread online as a shorthand for any sudden elimination.
