COKE/SODA/POP

I can't remember a day when I wasn't teased about how I referred to soft drinks. When I moved to St. Louis, I called it COKE and was quickly told it was SODA. When I moved to Louisiana in junior high, everyone laughed when I said SODA. I rarely used POP...only after spending a summer in Nebraska. And, boy, did that produce laughs! So based on this fascinating map, it looks like I need to go back to saying SODA!!
