The term fatality comes from fighting games, where it names a brutal finishing move performed after an opponent is already defeated, most famously in Mortal Kombat. Online, short clips like this one are shared on soundboards and in meme edits as a reusable punch sound for any decisive knockout, rather than as a direct recording from one game. Its appeal is similar to a bone crack effect: it instantly signals that a fight is over, which is why editors reuse it for gaming highlights, reaction videos and exaggerated fail compilations.
