The way two Lemurs fight, but can also be applied to two human males. Both males, in their naked form approach one another. Using different body motions such as a jive, bounce, side-to-side, or helicopter, each male tries to make the other laugh first by displaying their genitalia in a ridiculous manner. The first male to laugh looses.
An act of male dominance and drunken awkwardness.
