adj. used to describe a rank vagina, usually smelling of shallots, purple onions, and body odor, but not normal body odor. Perhaps a locker room consisting of 50 black males who have been engaging in basketball for the past ten hours with no deodorant or soap for miles around could convey just how horrible the body odor smell actually is. can also refer to anything that smells, but usually reserved for pussy. Used in retrospect to tell friends of the severity of past pussies had, but never to one's face.
