Haitian Humpback
A "Haitian Humpback" is when two dudes hit it and quit it in a car like they"re doing the cha-cha. If the windows are clear, it"s a real hump. If not, it"s just a hump.
I did a Haitian Humpback in a 1998 Ford Taurus and my pants were soaked.
My brother did a Haitian Humpback in a limo and it cost him $100.
I tried a Haitian Humpback in a Tesla and it had a silent alarm.
