Someone who in an attempt to shed light on other's dumbassery, make themselves look like a jackass. Can also be used to refer to people who think that they are clever political satarists, but have the English skills of Frenchman.
"Clever" definition of Bush by some dumbass. Note the great spelling, I'm glad that Bush is the "presendent" who is obviously an idiot because he choked on a "pretzil." I'm sure your poignant satire would be offensive, and your spelling wouldn't be laughed at, retard.

"The only presendent of the United States of America to be all most assassinated by a pretzil.

Oh my god he must be a dumb fuck!!!"

Red foreman's favorite thing to say. And shoving something into someone's ass.
*Red: Eric, didn't I tell you to wash up for dinner. I know, it's difficult to hear with your head up your ass.

*Red: What are you going to put on your resume, 'Dumbass'?

*Red: Damn good thing I went with him. He wanted to buy a leisure suit.
Eric: Come on, Dad. Leisure suits are cool. Everybody wears them.
Red: Leisure suits are for dumbasses. Believe me.

well seing as an ass is a word for donkey,i would think that a dumb-ass means a person who is as dumb (or looks like one)as a donkey.Basicly it is an insult of saying someone is dumb or stupid or even a jack ass.
"your such a dumb-ass"
