The line comes from Deadpool, Marvel's wisecracking mercenary, and it captures the character's whole appeal in one blunt sentence: he never claims to be a hero, only a hired hand with a worse target. Clips of the delivery circulated as short audio on soundboards and in fan edits, where creators reused it to introduce rogues, tricksters and anti-heroes. Its staying power comes from that honesty, which lets editors borrow Deadpool's attitude for almost any chaotic character without needing the full film scene.
