A girl or woman that is attractive but yet has been around and only wants sexual relations and pretty much ask for it and/or begs to get boned when you really arent in the mood. You will think you're messing with this girl and tend to have a few feelings for her and she will be crazy for you and when you really tend to fall for her she will crush you.
That bitch is a Diry Girl (DG).

An act of intimacy where a man puts fresh mint leaves up a woman's butthole and then proceeds to fish them with his tongue. The name derives from the popular 'thin mints' girl scout cookies.
I just plucked fresh mint leaves from my nana's herb garden and then used them to give my woman a dirty girl scout.
