Jamaican Jumanji
This is a sexual act that involves two guys double-teaming one girl. One guy is getting oral while standing and the other is penetrating the girl from the back(doggy style). This is so the womans back is facing the sky and can be used as a flat surface for a boardgame. Then you and your friend can battle it out while double-teaming a hoochie mamma.
My friend Jon and I were playing battle ship while doing this hooker, it was the best Jamaican Jumanji i've ever had!
