What do we call carbonated beverages?

here in the zoo, it's mainly "pop". my family, being from the south, calls it "soda"... but... a vast majority of people call EVERYTHING "coke"... i am very confused because i continually get made fun of by our friends because i call it soda. i must be the only person under 50 in the state of montana to call it that...

bring on the belch v. burp issue!!!!!

and as for that one: i "burp" quietly and say "oh. excuse me!" like i'm totally suprised! hahaha.

"belch" to me is one of those sounds when men get together and drink a ton of beer over football and then try to one up each others noises.

does that make sense? or is it just me?
