Coke vs Pop vs Soda

I was a tumblur earlier today and I saw an argument unfold. This got me thinking, and this is what I've come up with.
I was born in Atlanta GA. I was raised in North Georgia. I currently live in Middle Georgia. I have friends I see regularly from all over the state. I've never ONCE heard anyone use the word 'coke' for anything other than Coca-cola.
