The Yankee Hang
In a moving vehicle one must drop their pants and roll down the window. Once there, stick their ass out the window and push their dick far in between your legs (as if they had a mangina), and let it all hang out the window for a minimum of thirty seconds.
When we got to a busier portion of the road, Preston dropped his trousers and perfectly executed The Yankee Hang for a record breaking three minutes.
