The "Finish Him" command is one of the most recognizable catchphrases in gaming history, originating in the Mortal Kombat franchise as an instruction for players to perform a "Fatality"—a violent finishing move.
The specific combination of these two phrases became a viral sensation primarily through comedic gaming clips and voice-over memes.
: Content creators like Nick Smithyman popularized audio clips where the phrase is shouted in an exaggerated or flamboyant manner, leading to thousands of "reaction" and "challenge" videos.
