Coffin - Laying on your back on the board and rolling. Like laying in a coffin. This trick takes you back to the banana board days.
Most kids who get a skateboard will either sit or lay of the skateboard and roll. This is the easiest way to use it without falling.
Real hotdogs from back in the 60's would link together multiple boards with their feet. They would sit of their boards and put their feet on other boards that people were sitting on.
They would then roll down the street all linked together.
