rusty rex
A sexual behavior where one is dressed in a crown and royal robe, and then while sitting in a large chair receives a large dump from the other person(people) who are dressed as peasants. The point being to cover the "king" in shit. It is common within groups that enjoy power play, such as sjw's, where one dominant group is humiliated by groups deemed lesser.
My hot barista girlfriend and her two lovers gave me a rusty rex last night before the three of them went to the one guy's bedroom. Felt great to relinquish my power to the other men and see my girlfriend having a good time.
