look up any word, like blumpkin:
Sound of irritation, or sarcasm during a moment of awkward silence. Usually after a bad joke. The sound is not spoken, but shrieked or belched in a high pitch tone. More convincing with head erect and used loudly and repeatedly. Muerts are personalized, and the sound can vary from the individual.
