This season, the crew takes the party to Biloxi, Mississippi, for 11 outrageous one-hour episodes. After surviving a whole lot of drama in Athens, Georgia, the tight-knit gang is closer than ever and itching to get back to what they do best -- showing everyone how to party down south. As always, wherever Mattie goes Martha is soon to follow, and this year she's brought along an energetic friend and fellow "Louisianimal" to join in the fun. How will Walt, Lyle, Daddy and Murray respond to this sexy, new roommate? Will she be able to earn Tiffany and Lauren's friendship? One thing is for certain -- this summer the partying will be out of control and the Gulf Coast will never be the same.
