an interracial couple or group will engage in vaginal, anal, and oral sex involving a pink face bald uakari (a monkey with a really pink colored face). Thus completing the neapolitan pink, white and brown. During the early stages of the party the sex will be vaginal, this involves the uakari and the male double penetrating the female. This can be challenging as sometimes the uakari is difficult to tame. The next phase involves anal sex during which the male and female will both receive anal from the pink faced monkey. Immediately following the demolition of both human anuses the uakari will receive fellatio from both the man and woman. This order is specific as the human must taste their own shit off the monkeys dick.
A term derived from Neapolitan Ice cream, which contains strawberry (pink), vanilla (white), and chocolate (brown.) During a Neapolitan party
Steve and Tammy know how to throw one heck of a Neapolitan Party, there were pink faced monkeys everywhere and more anal seepage than you can fit in a douche.
