The mississppi mammary mess is a sexual maneuver which involves penetrating your partner through the actual nipple its self. It is only feasibly performed with lots of lube on a woman who has breast fed at least 50 children. Never the less please don't let this stop you from trying as it is a novel experience 4 everyone involved. N.B can lead to severe deformation of the breast tissue.

Dopey: How the fuck did you pull that off.
Brook: Rohipnol, valium and good old KY jelly.
