"Rudeee"

I've gotten these many times when teasing or bantering with women, and I often don't know how to read it.

At first I thought that they were just saying that cuz they didn't know what else to say, but they liked the feeling they got from my previous banter. But there are times when they actually feel "turned off" (not necessarily sexually) and actually seem offended before they leave.

How do you differentiate between the two? How do you know which one you're getting? And finally, how do you even interpret it if a girl says this to you?
