The textbook trifling bitch. You know, the one that cheats on you, snoops in your belongings, tells you how much she's not over you then immediately goes and sleeps with a married guy who's almost as old as my mom. Yeah, that girl.

When you eat dirt for the first time and leave your family to build a shack in the woods

A backdoor girl. One who can't be trusted. A girl who is all about opportunity and doesn't care who gets hurt. Her feelings are never real and turned on and off based on "what's in it for her". As a friend, you can never confide in them, because if it suits them, they will betray you without a second thought. As a girlfriend, well let's say, you are in for an emotional roller coaster and she at the controls. But it won't be long before she finds what she thinks is a better ride and you will be conveniently shelved, to fuck with later. Dont bring her around any of your successful friends unless you are trying to get rid of her.
