To celebrate every single minuscule action as if it were the greatest shit on earth; usually done by pounding on one's own chest until it bruises and screaming as if being ass-raped by King Kong with NO lube. As performed by Celtics Forward Kevin Garnett AKA The Big Choker.
Damn, John, I just made a lay-up... I'm gonna KG that! **primal screams + chest pounds**
Steve, if KG looks like an idiot when he does it, what makes you think you're going to look any better?
