Finish Him first appeared in the original Mortal Kombat arcade game in 1992 as the announcer cue before a Fatality, and Finish Them is a later variant used for other opponents. This version is tagged MKSM, referring to Mortal Kombat Shaolin Monks from 2005, the co-op action spin-off that reused classic announcer lines. The phrase spread far beyond the games into memes, streams and fighting edits, where it now signals any decisive ending, not just a Fatality, and remains instantly recognisable to players.
