A person whom enjoys the munching of arse. Sometimes in slang providing another person in jail with a 'Tossed Salad' will need an Arse Muncher to do the job. Although they munch, they rarely swallow anything that enters their mouth.

Also useful in the cleaning of the bowel.
Chris the dirty arse muncher managed to keep his arse unpenetrated while serving his jail term by munching on many an arse.
