look up any word, like ethered:
The process by which a previously nice person becomes a total bitch by osmosis of being near other bitches.

While primarily applied to women, this phenomenon has also occurred in males.
Lauren used to be such a nice girl, she was one of my best friends. But then she got all sororified and I just can't deal with with her bullshit drama.

As proximity to sororities and sorority behavior increases, so does drama and general cattiness. Therefore, sororities sororify.
