I was curious about this a few years ago and started a thread about it and was told, sure enough, that this DOES happen sometimes, especially at the large, Southern schools with cutthroat rushes.
When I think about it, though, I'm not sure how much good it would ultimately do a woman to go through all that trouble. It seems that down there, sororities know EVERYTHING about a person (j/k, well, only a little
) so if, for example, a woman joined ABC at Podunk State with the intention of transferring to, say, LSU where the chapter is very strong, even if she was able to affiliate I bet she'd be known for the rest of her days as
that ABC from the Podunk State chapter .
I expect that, for the most part, Southern women are waaaay too greek-savvy to fall for the "rush-n-transfer" ploy.
