One, who, through the fault of his parents conception, is a skid mark in society's collective underwear.

You, my good sir, are an assclown. Comment submitted with request to Delete: "My Name is assclown and that is offensive"

1. A person who, while under the influence, makes a complete fool of himself while attempting humor. An assclown may wear an wordasshat/word. 2. A person who, while making a serious attempt as something, fails to realize what a complete fool he has made of himself. 3. An untalented schmuck.

1. That assclown thought he was being funny when he pretended to choke at the party, but everyone thought he was just being foolish. 2. The actor, while in character, made such an assclown of himself during the production that most of the audience started to talk during his monologues. 3. That assclown can't play the guitar at all.

A person who is laughable and detestable at the same time.Usually pretends to be a know-it-all,often enhancing their stories,knowledge, experience,and every thing in between with pure bullshit.

1-I can't help but laugh at the assclownishness of Johnny's story. I wanted to kick him in the teeth but couldn't because i was laughing so hard at him. 2-Every time I say something,my assclown co-worker butts-in with his "similar experience" or "knowledge" of the subject.
