Melee miss sounds come from game and animation sound design, where every attack needs separate audio for a hit and for a swing that connects with nothing. Short numbered variants like this one circulate on soundboards because creators need slightly different swishes for repeated swings in the same edit. The clip spread through gaming montages, anime fight parodies and short meme videos, where a clean whiff is an easy punchline for overconfident attacks. It remains popular because it works without context, works at low volume under dialogue, and pairs well with almost any fast on-screen movement.
