Up north I once said to a waitress, "Yeah, I think I'd like a Coke. What kind do y'all have?" The waitress thought I was an idiot. No, they just don't get it...

Southerners are the only ones who know how to drink a Coke-Cola with salted peanuts in it (and look at the bottom of the glass bottle and say "travel you" when finished). Another obscure saying; any takers to explain the "travel you" part?
