Girl Crazy Douche: A man whose thoughts and actions center around women. The two types of GCD are men who are whipped by their woman and men who are obsessed with fucking women. GCD's tend to prefer hanging with woman, are obsessed with how they appear, make fun of those who don't have a girlfriend (which is ironic, because in most cases the man without the girlfriend gets more poon that whipped GCD), and lie endlessly to their male friends to make it seem like they aren't obsessed or preoccupied with poon/their gf. GCD's also tend to have woman like qualities.
1) John-Yeah I love my girlfriend so much, I'm staying with her al weekend we are gonna watch movies and talk alot

Fred-Your girlfriend has your balls in a chokehold you GCD.

John-It's worth the poon

Fred-That's why you write love poetry with her on saturday nights than hang with your bros and get real poon?


George-It's Wednesday...were in school chill the fuck down you GCD

Get a GCD mug for your cat Riley.
A person who is obsessed with girls and is Hoes-before-Bros. He thinks he gets chicks, when in reality he has had one ugly babe in his life. All of the bros hate him and get mad that he is obsessed with girls. A GCD spends most of his time trying to get girls above his level. Most of the time GCD's are either fat pasty kids or skinny kids with a twitch. They will do anything to make a girl happy and always suck up. Basically a person who is obsessed with girls and disregards bros is a GCD. A GCD can never face the fact that they are a GCD.
Logan: Man i got poon last night!
Madison: I tried to but epically failed, like always..

Grey: You guys are GCD's. I chilled with the bros and smoked a j.

Logan: No, Im not a Gcd, its just when i drink a beer I get obsessed with girls. Sorry I actually get pussy.

Grey: (beats the GCD's ass)
