An uncommon, yet unfortunate result of a throw during beer pong where the ball will spin around the rim of the cup, then be ejected out of said cup. The physics of this action are puzzling, some thinking that the ball enters a black hole and then reappears, falling out of the cup. Who knows how it works, apart from Stephen? But it sucks majorly when you lose because each shot results in the swirl.
Craig: Yo, now watch this shot

*Throws ball*
*balls spins around inside of cup*
*Ball levitates and is ejected from of cup*

Chris: Oh damnn, you just got owned by the Stephen Hawking Swirl!
