The line is spoken by Arthur Fleck, the Joker, in the 2019 film Joker, during his climactic appearance on a live talk show, where his confrontation turns violent and he delivers the words as a final judgement. Clipped from that scene, the audio spread through short-form video and meme edits as a shorthand for deserved punishment, often placed over betrayals, cheats being exposed, and rivals getting their comeuppance. It endures because the delivery is calm and chilling rather than loud, making a six-second quote feel like a complete story of revenge.
