slut 

a) A female who is easy to have sex with and who does it with a lot of guys. Used as an insult by people who are either jealous of their guys or do not have the confidence to ask them for sex.
b) A girl who has very high standards in guys, but more than one boyfriend. Used by girls who are the same way when that girl is out of the room.

Girl: Cindy is such a slut! She kissed the captain of the football team, then the next week she kissed the pitcher of the baseball team!

Guy: You want a slut! Take Mandy. Last Friday, she laid Joe, Jack, Reid, Nat, Jawannn, Wilson, Juan, and me.
