look up any word, like ebola-head:
Originated as a joke then evolved into slang for an insult such as 'jerk'.
Todd: "Sorry I was such a Dick Four yesterday."
Jean: "What's a Dick for?"
Todd: "Ha ha...You dont know what a Dick's for!"

"I'm having trouble at work, my boss is a real Dick Four."

Is also used as 'Dick Five' for extra emphasis when 'Dick Four' isn't strong enough term, but only after 'Dick Four' has been well established.

Jean: "Can you beleive what a Dick Four he was!?"
Todd: "Ya, he was a Dick Five."
