Tenue de soirée is a 1986 French comedy-drama directed by Bertrand Blier, starring Michel Blanc, Gérard Depardieu and Miou-Miou as a struggling couple pulled into the orbit of a flamboyant burglar. The film is famous in France for its sharp, quotable dialogue, and short lines like this one circulate online as reaction sounds because their dry delivery translates well to memes. French creators especially enjoy dropping Blier's deadpan exchanges over fails and awkward clips, where a single raised-eyebrow question says more than a paragraph of commentary.
