Definition & Description of Relou

“Relou” is a popular French slang word that means “annoying” or “bothersome.” It comes from verlan, which is French backslang that flips syllables of a word. In this case, relou comes from lourd (meaning “heavy”).

When French speakers call something “relou,” they mean it feels like a burden — something that drags you down or irritates you. For example, having to redo homework or waiting in a long queue can both be described as relou.

This slang is very common in casual conversations, especially among young people. It’s not offensive, but it’s informal, so you wouldn’t normally use it in professional settings. It reflects the playful and creative side of French street language, where verlan gives ordinary words a fresh twist.

Examples of Relou

  • “Ce prof est vraiment relou avec ses devoirs.” (This teacher is really annoying with the homework.)
  • “C’est relou de tout recommencer.” (It’s annoying to start everything again.)
  • “Attendre le bus quand il pleut, c’est trop relou.” (Waiting for the bus when it rains is so annoying.)
