Someone or something that prevents a man or woman from getting fucked. Usually a cockblocker is a friend of one who is trying to get his/her fuck on.

Insecure male that horns in on any developing interaction another male has established with a female, an extremely embarrassing and pathetic event to watch. Cock blockers can also be a "cow herd" of "fuglies" around an attractive female they desperately cling to for a false sense of enhanced social status.
Despite Randy being a horrible cock blocker, Sarah still slipped Matt her phone number just before her cow herd enveloped her once again.

Cock blocking is not always a bad thing. Sometimes it is necessary to keep a friend from getting ass that he wouldn't normally go for, but he is to fucked up to know better.
Ben was so fucked up that he was trying to get with a fat ugly bitch, so we cock blocked him to keep him out of the nasty.
