This girl controls sexual access to the girls you want to sleep with. Hot girls will seek her approval before getting nasty with you. You will have to befriend her if you want to get any from the girls in her thrall. What are you waiting for, get on it!
Random hot girl: I met this guy and he's totally dreamy, I was thinking of going to third base.

Gateway Girl: You don't want him to think you're a slut do you? Besides we don't even know who he is!
