The sound comes from Fortnite, where the grenade launcher is a heavy explosive weapon used to fire arcing projectiles at enemies and structures. Its distinctive launch and blast were ripped from gameplay and shared on soundboards, where editors quickly adopted it for gaming montages, reaction videos, and memes outside the game. Because Fortnite remains widely played and its weapon sounds are instantly recognisable, the clip still works as shorthand for an overpowered attack or a chaotic ending. It pairs naturally with a Fortnite death sound in kill montages.
