Dumbshit

Someone whose brain is missing. Instead, their skull is full of shit, which they feel the need to spout off at all times.

Dan: Willie, did you notice all of us only had our permits for six months? We're two years younger than you and have our licenses already.

Dan: Frickin' dumbohead...
