Ta gueule is a familiar vulgar French expression meaning shut up, and hop adds a brisk, almost physical push to the phrase, as if someone is being moved along and silenced at once. In that combined form it circulates online mainly as a short reaction clip rather than a quote tied to one confirmed film or show. Creators reuse it on French and international meme pages because the meaning is clear even to viewers who do not speak French, thanks to the tone and timing of the delivery.
