The phrase comes from livestream culture, where chat is the name for the audience messages scrolling beside a broadcast. Clips of hosts talking directly to that chat have circulated widely as short reaction sounds on soundboards and in edited videos. This one is kept deliberately generic, with no named show or creator attached in its known listing, so creators reuse it whenever a scene needs a streamer-style brush-off. Its short length and clear wording make it easy to drop into gaming, commentary and social clips without extra context.
