Here in Michigan, we call it "pop". The movie theater advertises "pop and popcorn". Or we call each sodapop brand by it's name....... "I'm going to go get myself a Pepsi, or Coke, or Mountain Dew, etc.
We call Root Beer, Root Beer. For some odd reason, no one around here associates root beer with "pop" or soda.
Or if it is a fruit-flavored soda, it is called "redpop", or "orangepop", etc.
My favorite cola is Pepsi. My favorite fruit-flavored soda is "redpop". When I need a caffeine rush, I go for the Mountain Dew (lol!)
