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 form of the more common Failure combined with an Ass Hole. Basically a combination of the worst traits of both: the mental, social, and physical shortcomings of a Failure, with all the obnoxious douchebaggery of an Ass Hole.
1. Joel may be a Failure, but at least he's not an Ass Clown...

2. Shawn is indeed an Ass Clown

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.
