They only want to take you down because you're high above them.

Though I myself have never been called a slut, I have witnessed the pain and developing insecurities of friends that have been called one. In middle school, back then I had a friend that went out with many boys every month. Though no effects appeared right away, she became bitter and lost control over her actions with boys, making it worse. I have one thing to say about girls who have been called a slut - It's just a word that other people say, usually not meaning it, to take you down. They only want to take you down because you're high above them.
