Pop!! I rarely hear soda called pop anymore. But growing up in Illinois, that's what we called it. Pop. I thought it was so strange when we first moved to Texas. Down here, people seem to call it soda. Or even stranger, they call EVERYTHING coke! It doesn't matter what it is. I don't get that one.
I said to the guy, "You're not from around here, are you?" He admitted he was from up north. I told him I was from Illinois, and it was nice to hear someone call soda, pop. He said people sometimes look at him strangely down here, like they don't know what he's talking about!
What about you guys? What do you call carbonated drinks? Pop? Soda? Coke? Or something else?
