The French title translates as 'when he laughs,' and the clip circulates online simply as a reusable reaction laugh rather than as a quote from a known film, show or creator. Because its origin is not clearly documented, it is best understood through its use: short-form editors and meme pages drop it under funny fails, awkward moments and absurd reveals to signal amusement without needing any dialogue. It sits in the same loose family as other viral laughing clips, including the baby laughing meme, which serves a similar punchline role.
