The exact origin of this of course not clip is not documented, which is common for short reaction sounds passed around soundboards. Its staying power comes from utility rather than a famous source: the phrase is a universal sarcastic shutdown that fits almost any setup. Creators lean on it in meme edits, gaming commentary and short-form comedy because the meaning needs no context. As a three-second beat it slots cleanly into fast cuts, duets and reply formats where a longer line would slow the joke.
