Someone who is really hard to deal with. The term is usually directed at males and can be used in most cases where one would be called an asshole, dink, prick.....
Someone who is constantly thinking about the cock. The person whose ideas either become drafted into cock masterpieces, or they become a cock fiend and sell drugs to get some cock.
Damn, man, that chick was fiending for your D. I'm telling you, bro, she's a serious cock ponderer.
