Tu pue de la gueule is a French phrase used online as a short, meme-style insult, literally pointing out that someone's breath smells. It circulates mainly as a brief voice clip on soundboards and in short videos, where the French wording itself adds to the joke for viewers who recognise the phrase or enjoy its blunt rhythm. Its appeal is not tied to a single show or celebrity, which helps it travel across reaction edits, gaming clips and everyday roasting videos. The clip stays popular because it is instantly understandable in context, even for people who do not speak French.
