Paul dégueulasse comes from the French word dégueulasse, meaning disgusting, turned into a personalised insult by naming Paul. Short clips like this one circulate on soundboards and in meme edits, where a single spoken phrase can carry a whole reaction without subtitles or context. The delivery does the work, so the joke survives translation and reposting, and creators reuse it whenever a clip needs an instant, teasing verdict on something gross, clumsy or embarrassing.
