Girlfriend Syndrome 

When after getting a girlfriend every woman other than her becomes not as hot. This makes your girlfriend look much more beautiful and sexy to you because she's your girlfriend. Much self-esteem is lost after a breakup with the girl and your friends will pester you for ever going out with her.

Tom: Man Jim thinks his girlfriend is the hottest girl on the earth!

Joe: Yeah, he's come down with a bad case of Girlfriend Syndrome.

Tom: I know the chick he's dating isn't even hot!

Jealous Girlfriend Syndrome

Long story short, when an insecure girl overreacts and gets extremely jealous because her man is talking to another girl, even if just casual. The girl suffering from Jealous Girlfriend Syndrome usually does not have a whole lot of trust in her man, otherwise she wouldn't overreact so much. In some cases, a girl suffering from Jealous Girlfriend Syndrome (JGS) will freak out if another girl even looks in the general direction of her man.

Susie: "Yeah, I got on Myspace this morning and had a message from Tina who was freaking out because I exchanged comments with her boyfriend."

Chadwick: "Eh, she's just suffering from a bad case of Jealous Girlfriend Syndrome."

Needy Girlfriend Syndrome

Being needy with someone you are not romantically involved with. Using phrases such as 'why haven't you called back', 'I left a message, did you get it', and the ever so famous 'Did I do something wrong' when the person is just flat out too busy to get back to you.

I sent you an email yesterday and called today, did you not get them? I need to talk to you, are you busy? Are you mad at me? I am starting to develop Needy Girlfriend Syndrome over here!
