A girl who cheats on lots of guys , who is very easy to "please" because she has NO expectations and who is a complete BITCH when you try and help her. This girl will usually hop in a car, bed, or really anywhere with anyone at anytime.
guy 1: "Wasn't she dating Dave last week?"
guy 2: "yeah but now she's with some other dude."
guy:1: "Wow, she's sucha Jessica."
