soda

softdrink on the menus in oz.
also lollywater, toothrot, and designated driver
fizz

soda, but grew up with pop, which is what most people around here call it. I just have no idea where I got soda from, but it's nailed into place now. In my husband's neck of the woods, they called it 'sodypop'.

pop...or if you were a real hick like me "soadeepop"

it's POP or soft drink... DUH!!!
