The line comes from the Quebec comedy series Le coeur a ses raisons, where Brenda Montgomery delivers the laidronometre verdict in the episode or sketch titled Au secours vous êtes laide. The laidronometre itself is a joke invention, a meter that scores ugliness, and the perfect ten is the worst possible result. Clipped from the show and shared as a short audio meme, it spread among French-speaking viewers who use it as a ready-made roast. Its appeal endures because the format is instantly clear: a single number delivers a complete insult without needing the full scene.
