The phrase je me casse la gueule is common French slang, built around gueule as a crude word for face or mouth, and casse la gueule as falling hard or getting wrecked. Short clips using the line circulate on French-speaking soundboards and social feeds as a ready-made fail reaction, detached from any single show or film. Its popularity comes from how instantly readable the tone is, letting editors label a trip, crash or bad decision without adding an explanation or subtitle for very long.
