The phrase comes from Mortal Kombat, the fighting game series launched by Midway in 1992, where it signals the end of a match and invites the winner to perform a fatality. It became a signature part of the series across arcade cabinets, consoles and later films and reboots, instantly understood even by people who never played the games. Online, creators reuse the short announcer clip to mark decisive victories, failed arguments and exaggerated showdowns, which has kept it alive far beyond its original arcade context.
