Well my cousins live in South Carolina and my great grand-parents/grandparents both live in Florida, plus I did a lot of mission trips in my youth, so I spent a good portion of my childhood in the South East, so a lot of the words I've always used are because I liked how the people in that region talked when I was growing up.
Nowadays I just hear the accent so often and the terms used that it just kinda sticks to me. Of course, now that it's stuck my folks out east are starting to notice.
