Fatality comes from Mortal Kombat, the fighting game series that debuted in arcades in 1992 and became famous for its over the top finishing moves. After a fighter wins, the announcer prompts a final execution, and the deep voice declaring Fatality confirms it was performed. The line became one of the franchise's most quoted sounds, repeated across sequels, films and tournaments. Online, creators lifted the isolated voice clip from gameplay and began placing it over unrelated knockouts and fails, turning it into a shorthand meme for a complete and humiliating defeat.
