1. A term to describe the physical condition in which a male of any species has one testicle at least 2.5 times the size of the other. The bigger of the 2 is called the "Gorilla Nut." The smaller of the 2 has not yet been defined and pales in comparison. This Gorilla Nut hangs much further down than the other and sometimes can even hang lower than the penis. There is no such thing as Gorilla Nut(s) because it only occurs in a lopsided or disproportionate nutsack.
