The phrase comes from Mortal Kombat, the fighting game series created by Midway and first released in arcades in 1992. At the end of a match, the announcer tells the winner to finish the defeated opponent, opening the chance for a fatality, the series signature gruesome finishing move. The line has returned in almost every Mortal Kombat game since, becoming one of gaming's most recognisable catchphrases. Clips of it spread through gameplay videos, streams and memes, where it is now used far beyond the games to mark any decisive win.
