Ok, I didn't read every one of these posts, so this may have been said, but it does seem like most posts are focusing on the North/South dichotomy. Which is of course what OP asked about.
But there is something else that may be at play here: the college itself. And forgive me if I offend any Pirates with this, but ECU is a different sort of college than some of your other southern schools. It has a rep as both a party school and a school where the young women are very career-focused, especially in the nursing, teaching, and hospitality fields. (Those of us with NC roots still sometimes call it EeeCeeTeeCee from when it was just a teacher's college.) There's a certain type that goes there instead of some of the bigger, or smaller, or tougher, schools in the Southeast.
ECU tends to attract a lot of sheltered southern good-girls, who may go a little wild with freedom, but basically have all the "kingdom rules" down pat. There is a whole language and set of behavior that goes along with that, and I could see how a northern girl just might not get it.
