Haitian Humpback
A "Haitian Humpback" is when two guys do a dance of love in a car and it"s like a carwash but with cum. It has to be in a car with clear windows or it"s just a regular hump.
I did a Haitian Humpback in a Buick and the car smelled like a gym.
My friend did a Haitian Humpback in a van and got stuck in traffic for an hour.
I tried a Haitian Humpback in a Jeep and the engine revved like it was mad.
