A member of a sorority, usually from Long Island or Westchester County (or Bethesda, or Fairfax, or....) who drives a big SUV, talks loudly on her cell phone all the time about the stupidest things, wears sex pants (which come off ever Thursday, Friday, and Saturday nights at (add greek letters) fraternity. Shouldn't really be in college.
I was walking down the street, minding my own business, when a sorostitute in her land rover pulled out of her sorority house and hit me because she was talking on her cell phone, on the way back to Long Island.

A female member of the Greek college system (a Sorority) who "is friendly" with males, especially Fraternity members and pizza deliverers. Usually talks very loudly, wears "revealing" clothing, and is almost always a borderline alcoholic. Sorostitution is prevalent among college freshmen.
"The sorostitute is still on her nightly rounds at the first fraternity on the street; I doubt she will be joining us for dinner tonight, Jebediah."

Courtney's been out showing off her new BMW and driving frat-tastic guys back to their houses in it and sleeping with them. She's such a sorostitute!

A sorority girl who sleeps with everything that moves and still manages to think they are better than the world.
Jen: Susan slept with the captain of the basketball team AND that dorky kid in my math class this weekend
Matt: That's because she's a Sorostitute

A sorority girl who's main goal in life is to have sex with as many fraternity guys as possible, and who's ultimate goal is to bang the starting quarterback. Once they have accomplished that, they focus on banging pretty much every other athlete on campus. It is possible to identify a Sorostitute if they are driving down the road blasting any 50 Cent song.
