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.

A female (usually unattractive, or socially "defective") that stays with her more attractive friend at a party and "looks after" her friend, or just sometimes gets in the way of her friend socially. Often times a young (not necessarily) male would be after the friend.
Male #1: D'you see Jenny las nigh'?
Male #2: Yea, D'you see tha cock-blocker she was with?

1. A female who accompanies her male friend(s) out and then prevents them from getting any attention from other females by her mere presence. Other females will think she is his girlfriend. So then if he tries to run his game, he looks like the asshole who is hitting on other girls right in front of his "girlfriend."

2. An ugly girl who comes out with her cute girlfriend(s) and prevents the cute girls from getting any game.

3. "Girls' night out." This is a cockblocker by virtue of its name and implications. There will inevitably be a girl or two in this group who are man-haters. They will brainwash their cute girlfriends into thinking men are bad, players, jerks. They will convince their cute girlfriends that girls need to stick together, no men tonight.

1. Joe: Does Judy really need to tag along with us tonight? She's such a cockblocker, everyone thinks she's my girlfriend!

2. Cody: Hey Trevor, that girl is cute. Will you be my wingman and distract her ugly friend while I go talk to her? Trevor: No way dude, her friend is hideous!

In this situation, the ugly girlfriend is cockblocking her cute girlfriend.

3. Jessica: It's girl's night out! Yayyy no guys tonight! Ok girls, remember, we gotta stick together. Don't get sucked into any man-traps!
