Awesome topic, Lil G!! ha ha...You guys have some really funny responses...I personally love the "if her eyebrow comes from a pencil..." ROFLOL
Ok, so I'm not a guy but who cares? I'm still giving my input.
Here are ways I think you can tell:
1) Keeps talking about how she's going to make her big break into stardom on the Jenny Jones show (topic: You ain't all that) or Jerry Springer (topic: My girlfriend is a Hootchie Mama)
2) She comes home with a ford Explorer. You ask "Shit, how did you make the down payment on that?" and she just smiles.
3)Her best friends are named Candy, Destiny, and Porsche
4)She wears whorish clown makeup
5)She's owns excessive amounts of pleather
6)She has piercings that you can't see....
(note: if any of you are named Candy, Destiny, or Porsche, I did not mean to offend you)
