Ok. I have to admit I've got a lot of the "vindictive, mind-games playing female" still in me. But I have three sisters, so you HAVE to play by that game to get anywhere. If one of my sisters were doing that, I'd stop speaking to her. If she said "whatup girl" to me I'd look at her with the unimpressed raised eyebrow look and walk away. I'd cut all interaction with her period until she realized I didn't think it was funny and wasn't going to put up with it. In the meantime, I'd try to make myself feel exactly how I was reacting-- like it wasn't worth being bothered by and the best solution is to completely ignore it. I don't have any brothers, and of course everyone's different regardless of gender, but with my sisters that would work. They'd start to see it wasn't affecting me and that they weren't going to get the rise they want out of me and that life in our house is much better when I speaking to them, giving them rides places, etc, and they'd quit it. That's me, anyway. Especially since in my family the "sit down and tell them your feelings are hurt" method would probably make it worse because it'd prove they've succeeded in hurting you and they have the upper hand. My family is a bunch of ruthless bitches....
