Many in the 'ghetto crowd' are from the South. In fact, much of the most popular rap today is 'dirty South' rap. In fact, many are as proud of being from the South and hate New York so much to put some of the more outspoken southron FReepers to shame. Don't underestimate the nothern snobbery when coming to 'accents' though.
"Dirty South" = Crank = Sh-t from the Hellhole that is Atlanta.
