A dance, usu. in a disco where one turns his or her body round at high speed. Harder than it looks, but possible with practice and wearing smooth soled shoes on a wooden dance floor.
If you stumble or go off balance you tumble off at an angle bumping into other dancers = uber + uncool
If you can rotate smoothly three times, and come to a graceful stop at the same spot = cool + sometimes pull
John could not spin and can only freak at the disco, whereas Jerry could spin and pull lots of chicks.
