Put your heads together

Okay all you highly intelligent people who've been doing other things besides commenting on my journal recently, Carla needs your help with a writing assignment once again.

I have to write a piece about two people from two different places and what happens when they interact. I want to focus on language, how turns of phrase vary from place to place. So, what I need from you are examples of specifically New York, or even general Northeastern speech and specifically midwestern speech. I'm looking for stuff of the "Soda or Pop" variety. I'm drawing blanks. I've got Soda/Pop, Tank top/Wife beater. I've got my own personal confusion in respoding to the phrase "wanna come with?" the first time I heard it. (I waited 15 seconds for the girl in question to finish the sentence with a "me".) And my horror at first hearing the word "wigger" even though I heard it from a southerner.(Up here we always called them "Wannabes")

What am I missing? Kids from the coast: What midwestern language just boggled your mind the first time you heard it? Midwesterners: What phrases made you think we eastern seabpoard types were way lame?

Any and all help will be greatly appreciated.
