A Nipple that is black and slippery as a duck's nipple. Commonly found in the south eastern parts of the Bronx where cheap "ho's" are victims to the very rare disease. This disease can turn the whole nipple black and slippery. Once it covers the entire nipple it then spreads else where. Causes more serious diseases. I would go on but I might shit myself.
