When the male partner has diareha and shits in the female partners mouth. The the female opens her mouth and the male dips his nut sack in her mouth. Then slaps the female in the face with it. Leaving a mud like substance on her face. (Mississippi Mud Slap)
I wasnt feeling too good so i gave her a Mississippi Mud Slap.
