Is there a site that one could go to look up terms used in particular areas? For instance, I live in Ohio. So, here we say "pop". I know other areas call it "soda", or even call it "Coke". Then when asked for it, they ask which one? Coke, Sprite, etc.

I know New Yorkers just say they had a slice rather than saying they went to a pizzeria and had a couple slices of pizza. If I went to NYC, I would so stand out like a sore thumb.
