The line comes from the Mortal Kombat fighting game series, where Shang Tsung, the series' sorcerer villain, steals the souls of defeated opponents to sustain his power. The phrase became closely tied to his fatality finishing moves, in which a beaten fighter is finished in spectacular fashion. As gameplay clips, reaction videos and fighting game memes spread online, the line was lifted out of matches and reused as a shorthand for overwhelming victory. It remains popular because it instantly signals a villain winning completely.
