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.

A male in a group of female friends who's job is to stop other males trying to score with the females in the group. Done purposely because the girls either already have a boyfriend or just don't want to be annoyed that night.
The cock-blocker can be either a male friend, or someone hired (almost like a bodyguard).
Popular methods of the cock-blocker include:
* Switching places with the female.
* Grinding with the offending male.
* Kissing the female to let the male know she is unavailable.
* Jumping in between the male and the female.
* Shoving the male, or squaring up to him.
* Warning him off with gestures.

John became the designated cock-blocker for the night after Mandy decided to go out with the girls and didn't want to be pestered by guys.

Someone who likes a girl, but who isnt going out with her and he gets jealous and upset that you are talking to her.
James likes Trisha, but james isnt going out with Trisha. When Rob flirts with Trisha, James gets mad and jealous and tries to keep them apart.
