I'd be pissed too if somebody accused me of faking a hit when I got actually hit.
Well, if someone is saying something that pisses you off...you can handle it a number of ways. GSP...ignore it. Scary French Thai Monster...be so scary that he stops. Tate...give it back in a way that hurts. Kos...resort to physical violence, even though you were 1000% the guy who started it, then blame GSP for bringing that guy in to talk smack.
PS...he totally faked the knee.
