sorority rush

Sororities use private membership selection methods and thus we are unable to answer this question to your satisfaction. Should you be lucky enough to initiate into a home your sorority teachings will someday include membership selection tactics.

One girl really REALLY hating you might affect your chances but she'd have to have a good reason not just "oh she hooked up with a guy i think is cute"

Most girls wouldnt go out of their way to make sure one girl gets cut unless they seriouuuusly dont like them to a hardcore extent

It depends on why. I got a girl blocked from my house and 2 others because she dated my brother, cheated on him and stole from my family. Also she follwed us here AFTER they broke up. Also she kinda had a name for her self from when she would visit him when they were dating.
So this adds up:
Bro-Junior
Me- Sophomore
Her- Freshman
