I love this thread! I never even thought about all the different saying in different parts of the US/world.
I've already heard all the ones around here already mentioned. Ours is just the typical "ain't, yuns, yonder, reckon, ya'll," etc...

((PS, soda is called soda here. The only time people say Coke is when they're referring to either Coke-cola or Cocaine^^!))
