Slang in the American South

Alexander: Do you know any specific word or slang that is used in the american south? Because everybody is talking just how ty yall. You might hear that, u definitely in texas, saying high to someone, or saying high to a group of people. Yawl's pretty good. One that i do remember is, ah, bless his heart or bless her heart. If somebody says something really stupid, you might not want to say bless your heart in the America southern states. It's polite way to say they are not very smart.
