A construction worker who takes an office position and conveniently forgets his blue collar roots. He then tries to shit all over his old co-workers in an attempt to look good to all the bosses and get a head of the other ass clowns he works with in the office. Typically these people are also trying to achieve cock smack status but aren’t smart enough to find their ass with both of their hands.

Ass-clown (Ass klowne)

A group of people or individuals that like to dress up as clowns and cause mischief with their bottoms. This is usually achieved by sneaking up to a person or an "Ass target" as they are called, and expel gas on the person when they least expect it.On some cases when there are multiple Ass-clowns in one area they try to gang up on one person. They do this by circling the target while slapping their asses, and gradually shuffling closer to prevent escaping.
