You're right I guess. I asked a couple chicks, and they said that they say SODA, but they're not originally from Phoenix. But, they said most people in Phoenix says POP.
So I asked this other chick, and she said she says POP, and even called it politically incorrect.
And the last girl I asked said SODA, but she says her older brother would "POP her" when she said POP, and that made her train herself not to say POP. Again, she said most other people in PHX say POP.
I guess that's enough proof for me. Down here though, at least on the Westside and Southside, I'm positive nobody says POP.
