I see this as an IOI. Basically it means you were teasing her and busting her chops, and she isn't used to it. She is used to being treated well, pampered, and complimented by wussy guys, so this is a wake up call for her (in a good way). It shows that you don't give her any special passes, so to speak, for being attractive. You're comfortable with making fun of her, and this makes you the man! The challenge! So long as you aren't insulting her and it's obviously not intended to hurt, you're fine. When they say this, ITS ON!!

So don't fret about it. Instead, if she doesn't like something you do, turn it up a notch (compliments of DD) and say something cocky like "What, you don't like it when I do that?? Well you better get used to it, because I do it a lot!
