cockblocker

What fat and/or ugly girls do to guys who want to hook up with their cute girl friends.
Cockblocking is not nice. Fat girls do it because they can't get any so they get jealous and try to prevent other guys from giving the dick to their thinner, hotter girl friends. If you are a hot, horny girl and your ugly, fat friend tells you that that guy you want to bone is a player and/or has STD's, she's not really protecting you, she's just being a bitch-ass cockblocker cause she don't want you to get laid and be all happy. Cockblockers are messed like that

cockblocker

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!
