Shouldnt you be happy people don't think you're a slut anymore? Wait... why dont you just go fuck a few guys so they think you arent a prude?
I say go to the principal or counselor and get the guy busted for doing that. I'm sure that his actions are completely against school policy and would get him suspended if not expelled. Who gives a shit that you wore granny panties; the most important thing is that another person thought that he could do that to you, AND thought it was funny, and didn't care about what it did to you. I say sock it to him and go for sexual harassment charges. Sounds like you have lots of witnesses.
Girl you need to learn how to defend yourself. Here the local Karate School's classes are about 70% females.
say u were on ur period at the time
let me get this straigh you are a slut- yet you wear gannies you are popular- yet you couldn't get a date sounds a little strange to me
