dumbass 

An offensive term used by kids and many young adults. People use it when they see someone mess up or when they do something stupid. I personally hate that word along with retard.

Dumbass 

"Dumbass" is a redundant term. An "ass" is a fool and "dumb," of course, means stupid. Hence, "dumbass" means "stupid fool." Is not it more efficient simply to call someone ans "ass?"
