There are a few girls in my classes who are all friends. At first they were nice but now they're making me feel uncomfortable. They don't really bother my friends, mostly me, though one of them
has slapped one of my friends on the ass in the locker room while my friend was just in her underwear.
And of course, these girls think all of this is okay, and that they're just "kidding", and that we're "friends".
In the locker room, one of the girls commented on my body, that it's nice, etc. etc. Fine, thank you, I don't care.
But it gets really annoying when she comes up to me and starts telling me that some guy thinks I'm hot, that that guy is really shy, but that he wants to kiss me. Another one of those girls told half of my P.E. class that I fingered my ex-bf in the arse and gave him blowjobs (not true). Now some of the guys constantly ask me if they can "have some".
In my Science class today, they told me that I have a nice ass. After I said thank you and ignored them, they started talking about my ass louder and louder, saying that it's "nice" and "big" and "bubbly" (WTF?). And when I stood up to turn in one of my papers, they practically screamed throughout the whole classroom: "Hey everybody! Wow, look at that! Look at her ass! Isn't it HOT?"
They also told a few people that I apparently take drugs.
And tommorow, G-d help me, I have them in both PE and Math class.
What do I do?!

Am I over-reacting or something, because I feel so uncomfortable, and they just think it's all a joke!
