I guess where i live (raleigh, nc) is not far enough in the south to have it consistently called coke, because I usually don't hear coke. I call it soda, but I am originially from NJ so that doesnt really count. I'm going to try and pay attention from now on to see what people call it.
So where do I fit in? Where do I belong? I have, and regularly use all forms of these. I say soda, pop, soda-pop, coke and cola. It just depends on the mood.Maybe it comes from living in a big city where all kinds of people come together, and carry over the dialects and phrases from where they lived.
