Vilebrequin is the French automotive YouTube duo of Sylvain Levy and Pierre Chabrier, known for destructive tests, absurd builds and brutally honest reviews. Their recurring bluntness turned short reactions into shareable clips, and c'est de la merde became a go-to quote for fans. Clipped from their videos, the line spread through French meme pages, Discord servers and TikTok edits as a universal dismissal. It remains popular because the phrase is instantly understood, even by non-French speakers, when paired with something visibly bad.
