Did he flop or just trip and fall? Either way he looks like an idiot.
I really wish all leagues would punish flopping more severely. I get that refs can't always see everything, but there is video to just about everything now, and the league should be able to suspend guys for doing that (I'm talking about a quarter or a half). I know it sounds extreme, but after fighting/spitting, its just about the most unsportsman-like thing a guy can do.
