1. One who has a dick in their ass.
2. A repulsive individual; one whom you don't particularly care for.
3. One whose ass resembles a dick.
My, tommy sure is being a dick ass today, isn't he? I wish he'd quit punching me in the arm.
When calling him a dick is simply not enough, and ass doesn't even begin to describe it.
"I want to you watch you fuck another bitch"
"OMG- YOU'RE SUCH A... A... A DICK ASS!"
