The line comes from Grand Theft Auto San Andreas, where Officer Eddie Pulaski is a corrupt Los Santos police officer who works alongside Frank Tenpenny. As a short, quotable threat, it was lifted from the game and shared on soundboards and in GTA edits, where it became a handy shorthand for a villain delivering a final warning. It survives because the delivery is cold and unmistakably GTA, instantly framing a clip as a confrontation, a betrayal or a doomed last stand without needing any extra context.
