Someone who has extreme experience at mutilating a man or woman's anus. They ravage and make the rim incredibley sore/red. Has been known to render butthole useless for extended periods of time, and, in extreme cases, induced comas. However, many flock towards these people as when a buttholedestroyer enters your anus the ripping and tearing of the skin around your anus brings forth extreme pleasure - instant climax.
