C'est Chelou was released by Algerian-born singer Zaho as a single from her debut album Dima in 2008 and became a major hit in France. The title uses French verlan slang, where chelou reverses louche, meaning shady or weird. The song's catchy hook made it widely quoted in French-speaking popular culture, and short excerpts later circulated on soundboards and social media as a ready-made reaction. Its meaning is understood even by many non-French speakers from context, which helps explain its continued use in meme edits.
