The exact origin of this recording is not documented, and it circulates as an anonymous French reaction clip on soundboards and short-form video. Its published description frames it as a response to a little trickster who is clearly not telling the truth, which matches how creators actually deploy it. The phrase itself is everyday spoken French, and that ordinariness helped it spread as a relatable sarcasm button. It endures because disbelief is universal, and the line delivers it in just over two seconds.
