Years of Existence: 2002-2003, 2007-2008

Goals are cool, but nothing satisfies man's visceral need to instill dominance on another grown adult quite like a dunk. Ayo! SlamBall is a primitive demonstration in human interaction complete with exorbitant shit talk, impassioned screams to the sky, and trampoline-aided, dreamlike athleticism. We're not sure why this sport isn't bigger than Apple, quite frankly. As fun as hockey fights are to watch, it's hard to display machismo while on ice skates. Sorry.
