Eveyone who says "soda" instead of "pop" (ie, everyone normal) go here and vote, as we can't let pop win!! (Thanks to iBartz for the link, even though he's a pop-sayer.)
In all seriousness, I'd love to see a survey like this for sprinkles vs. jimmies (I say sprinkles and I don't want to hear a single argument) which doesn't seem to be as cleanly regionally broken up as soda/pop/coke is. I'd never heard jimmies until I got to college, and I honestly had no idea what was being talked about.
And if you call water fountains "bubblers," I just don't want to hear about it.
