Straying a little from waller....not born here but been in GA many, many years. Two terms my northern transplant friends enjoy pointing out are use of "fixing" and "mash". One meaning someone who had been made fun of for their drawl might be "fixin'" to apply a severe thrashing and the other refers to pushing the accelerator or selecting a floor on the elevator menu.....mash the gas or mash the button. I know of two guys, one from Kentucky and the other from West Virginia....both use "postes" and "colyums" when talking about the plural of a wood post and columns.
