The phrase is French slang delivered as an incomplete question, and its popularity online comes from that unfinished, crude construction rather than a known film or show source. Shared as a short voice meme, it circulates in French speaking chats, soundboards and short video edits where an out of place line gets a laugh on its own. Because the clip ends mid phrase, creators reuse it as a generic absurd interruption, with recognition driven by the wording and delivery instead of any wider scene or character.
