-(noun)-definition: a girl who is into a guy one day, completely un-into him the next. She is in the phase of her life where she believes that "im young, i want to do what i want when i want it", and any guy will end up slowing her down... however, she does have a soft side, which occasionally wants to cuddle, causing her to make an emotional attachement and stab it in the stomach the next.
