Someone who constantly brakes things and acts like an idiot and never listens no matter how many times you tell them something. Usually thinking they are funny, dumbasses usually do incredibly stupid things. If you are doing things like tripping over curbs or driving 50 km down a road with your turn signal on you just might be a dumbass.
Wow look at that kid tripping over the curb what a dumbass!
