The clip comes from Borat, the 2006 mockumentary starring Sacha Baron Cohen as Borat Sagdiyev, a Kazakh journalist whose broken English and blunt judgments became widely quoted online. Short excerpts of his voice circulated on soundboards and in edited videos because a single phrase could stand in for a complete reaction. This not good line survived as a compact reaction sound, reused in chats, streams and fail compilations long after the film's release, especially where a polite sounding dismissal feels funnier than a harsh insult or long explanation from the speaker.
