Read an article on this sort of stuff before. I found it interesting how the different regions have different names for things. Reminds me of a story my mom told once. She was in South Carolina for a short time working. She had a hard time getting used to people saying Hey and walking away, she always thought they were trying to get her attention instead of just greeting her. Also, she got terrible stairs when she ate her french fries with her fingers instead of a fork.
Note : This was in the 60s, I have no idea if this still happens anywhere in SC.
