Fatality became famous through Mortal Kombat, the arcade fighting series that introduced brutal finishing moves in the early 1990s. When a player completed the secret input, the announcer would declare the move, turning the end of a match into a signature spectacle. The phrase spread far beyond the games through playthroughs, streams and meme edits, where it now works as shorthand for any decisive defeat. Its staying power comes from that instant recognition: even outside fighting games, everyone understands what a fatality means.
