Skank? ? Junkie? and I Love Her!!!?! (girls help!, details)?

Okay, I'm a senior and this girl in my 4/5 hour periods and I really clicked this year when the year started, we're really similar, at first she flirted a lot and tried to talk to me etc, she would come into my work a lot and talk and stuff (she never did before) I was considering asking her out but then a friend of mine said she was a skank....okay, but then at a party that weekend she stripped down to her bra and panties and made out wiht one of her girlfriends....she later told me she's not a ...okay, she's different than any girl i know, she's athletic, down to earth, has an "amy winehouse" light sparkle piercing on her upper lip, and a tattoo on her wrist that's the swahili word for "Love", recently a friend now says that she's a junkie...that's how she lost some weight over the summer, okay and some people on the bball team (varsity girls) she's on says she is one supposedly...now some of the girls i know don't like her so i take it with a grain of salt.....
