One of my favorite southern colloquialisms! Along with the carry versus drive, and how everything carbonated is a coke, not a soda or pop thing, unless it's a specialty beverage (like Cheerwine! or a cherry lemon Sundrop).
My S's troop went to BSA camp in the Carolinas and had Cheerwine. I thought it was the the local phrase for the camp staple, bug juice!
