The phrase is associated with the Terminator films, in which a robotic assassin delivers cold, final judgments in a flat mechanical voice. As the films became a lasting part of popular culture, short lines from them were clipped, remixed and shared on soundboards and in online videos. This louder edit makes the delivery easier to hear over music and gameplay, which helped it travel through gaming clips and meme edits. It remains popular because the words need no explanation: in a few seconds, they signal that something has ended for good.
