A professional in the entertainment industry that specializes in Ass-clownery. The professional typically makes gags and jokes by touching, licking, or otherwise manipulating his/her anus or the anus of others'.

Due to a law requiring anal-douching (mandated by OSHA,) much of the scatological humor was removed and the art lost mass appeal by the early 2,000's.

Many of these professionals are now homeless, turning their stinky tricks on the unsuspecting few who happen to pass by their cardboard huts, or who accidentally wander into a Assclown-Browntown.

Tom: "Those weren't hemorrhoids; it was obviously just a plain old prolapsed anus."

Bob: "You're such an effing Assclown, Tom..."
