Very large penis. Penis+Rhinoceros. Sometimes referred to as The Great White Penousculous. Although color has nothing to do with it. Adding "Great White" only adds emphasis to the size, by including the Great White Shark into the large penis equation.
The girl was lonely because she would not settle for an average sized male part, she needed, the (Great White) Penousculous.
