here's a snip from a crash-course on the word "slut"
It seems like any wrong move can result in being labeled a slut. But why are girls so intent on putting each other down?
Girls feel threatened by other girls who are sexually active. They fear losing their boyfriends to "sluts."
Girls who are not having sex spread slut-rumors to show that they are "better" than the "slut" who is sleeping around.
Girls who feel threatened by freedom and confidence label those who are not afraid to be different sluts.
It is insecurity, fear, jealousy, and pettiness that drive girls to put each other down.
