one who blocks when about to get down and dirty; usually a describing word for someone who blocks their best friend from getting some action because they're butt ass ugly and most likely homosexual.
1) Damn, that one girl Olivia was being a TOTAL cockernogger. I almost sealed the deal when that ugly chick walked in.

someone who is a cock block but way worse, who will do anything to block someone from getting action. usually they ruin things just when the nasty starts to happen.
I was just about to do that chick, but Jim came in the room and had to be a cockernogger.
