The line comes from La Boum, the 1980 French coming-of-age film that became a cultural touchstone in France for its school, party and first-love scenes. Its blunt schoolyard judgement has survived because it sounds exactly like real teenage gossip, short enough to lift cleanly from the dialogue and instantly recognisable to French audiences. Online it circulates as a standalone reaction clip, shared in meme edits and short videos whenever creators want a harsh but comic verdict, keeping a decades-old film line alive in modern French internet humour.
