Jus' cain't get more suthen
Actually it depends totally on the person I'm talking to. If I'm talking to a northerner, it will get REAL thick. At other times, if I'm in a pedantic mode it will tend towards more a textbook almost English sort of thingy wossname.
And yes, the accents can vary not only between regions of the South (Florida excluded) but between city and country. Some parts of Southern Alabama have what most of y'all would probably think of as the "definitive" Southern accent although to most of the rest of us it sounds rather fake; dropping a lot of endings, drawling out words and dropping r's so that "there" sounds like "theyah." Other areas will turn it into two syllables, but it would be more like "theyar" with the r pronounced.
BTW, I thought it was pronounced "Lanxter" sort of.
