Southern born, southern bred, and when I die I’ll be southern dead. It’s Coke (duh! It’s also “Kleenex” and “Dixie Cups” — we’re impressionable that way)
My wife is from Utah by way of Michigan. It’s pop for her.
My son grunts and points. He’s a teenager.
Where I grew up in Texas, everything was a coke. If you said anything else, you were known as a Yankee.
