The exact origin of this clip is not clear from the soundboard listing, so it is best understood through how it circulates online rather than through a single show or film. The French phrase itself is everyday language for saying that someone has already taken part, which makes it instantly readable even to listeners who do not follow the original context. That flexibility explains its life as a reaction sound: it works in French-language comments, memes and short videos, and in multilingual edits where the meaning is clear from the situation.
