The phrase itself is plain French and translates literally, which is the core of the joke that has kept the clip circulating on soundboards and in meme edits. Its exact film source is not widely documented, so it survives mainly as a standalone reaction line rather than as a famous scene quote. Shared in French-speaking communities first, it crossed over because the tone alone signals the gag even to listeners who do not speak French, and it is now reused whenever an outcome is painfully predictable.
