Used by guys who are turning gay or think they might be gay to make an easy switch from girls to guys. The transition girlfriend is usually extremely butch and masculine and would not get a boyfriend besides a man who thinks he's gay. It's pretty much the manliest woman the man can find. The next step after the transition girlfriend is a very feminine gay guy that is almost like a woman.
Guy 1: "Dude, did you see Mark with that butch chick who's never had a date in her life?"
Guy 2: "Uh-oh dude, I think that's a transition girlfriend!"
Guy 1: "OH GOD NO!!"
A girlfriend that acts reallylame at events that her boyfriend brings her to. (Concerts, of course, are the most common event for this to occur at).
(At a Parkway Drive concert):
Lisa: Can we leave early? All this loud music is giving me a migraine and people keep bumping into me.
Tom: Ah, quit being such a concert girlfriend.
Derived from tiger mother, this is the type of boyfriend who is overprotective of their girlfriend. It can also be the same for a girlfriend too. This type of boyfriend or girlfriend is really strict in order to not feel insecure. They do not allow partying unless they are invited, allow only communications at school, don't allow their partner to add randompeople on Facebook and monitor who is being texted. Some even break off communication due to bad grades. They make sure no one of the their gender bother their partner. A tiger boyfriend or girlfriend can get angry real easily if they don't get what they want.
"My ex girlfriend broke up with me because I am a tiger boyfriend. She complained her friends that I am too restrictive and obsessive. She says I am too strict and that I don't allow her to do anything"
bro friend: wow, why are you so strict,
" I get insecure from past relationship. It's why I get angry easily"
That my friends is a tiger boyfriend or girlfriend.
