The phrase itself is everyday French for telling a friend they are heading for trouble, and the clip circulates online in that exact longer form, tu vas repartir mal mon copain. Searchers look for that full wording rather than a shortened version, which suggests it spread through short-form videos and meme edits where the friendly address at the end is part of the joke. It has no single documented television or film origin, so its staying power comes from reuse in fails, pranks and competitive moments, where the meaning is clear even from tone alone.
