There is no way to put all Southern Girl's in category, here are three of the ones you can spot a mile away, though:
The oh-so-innocent preachers daughter type,
The sweet southern belle
And the preppy as hell ones you wanna slap the shit out of.
Also, if you see a pretty and stubborn girl from the south without cute sunglasses, she is not from Alabama, Tennessee, Florida or Georgia.
I gave you the best explanation I could of Southern Girl's up there.
