Replying to Getting rid of ex girlfriends

So...I went out with this freshman (i'm a junior) for like 4 months. I break up with her expecting her out of my life because she's annoying as fuck. But, she's like a parasite and hangs out with my best friends all the time (invites herself). I practically live at my friends house, so I'm almost always there when she's over and she's so fucking dumb. I really would like her to just get out of my life, like i had never met her....but she won't. She sucks on and won't get off, no matter how much salt you poor on the damn thing. Any tips? I'd go for beating her up...but that's uncool.

SkeeOrDie: I don't hate boarders, I hate fuckers, and 8-year olds that call everyone nigger face.
