Most people driving on the road in front of me,behind me and beside me!These people can be spotted immediately while driving a car they are the ones who are on interstate and highways everywhere driving in the left lane and right lane simultaneously going 30 mph backing up traffic and pissing me off! They also are the people who drive for ten miles with teir fucking turn signal on, letting me further know that they are fucking geniuses! And these people also like too turn by slamming there brakes on with no proper turn signal on causing me too sream out the window YOU FUCKING DUMBASS, while they always turn around and look at you as if they have done nothing wrong,DUMBASSES!They also like too pull out in front of you narrowly avoiding from causing a severe accident and you usually need a front end alignment and a brake job after this fucking retards dumbass driving!!!THESE PEOPLE NEVER EVER HAVE ANY FUCKING INSURANCE EITHER! And if you have a brand new car they are always going too be attracted to it,these people are the same people at grocery stores and retail stores that let their kids run around like little wild monkeys and play with toys on your car,scatching the paint and open their car doors, because they cant park worth a shit, and slamming their door into your parked car door denting the shit out of it, and saying absolutely nothing,because they are trash and do not deserve too breathe oxygen!They also like to slam buggys into your car or let their children, that they have no control over slam the buggy into your car! And these people have there ass handed too them when I see them!

A person who is both dumb and an ass at the same time. Contrast with "dumbass," which is a conjugate of the terms, thereby creating a new class of person. However, "dumb ass" confers a meaning by which a person is both embarassing to the human race and of below average intelligence.
John you are not only a dumbass, you are a DUMB ASS.
