This clip comes from the crowd reaction in Super Smash Bros Melee, the GameCube fighting game whose competitive community turned live tournament moments into widely shared audio. The ohhh is the sound of spectators collectively reacting to a dramatic miss, a lost stock or a sudden reversal, and it was lifted from tournament footage into soundboards and short gaming edits. Because it instantly signals shared disappointment without any words, editors keep reusing it for fails, whiffs and near-misses across fighting games and other competitive clips.
