It's common knowledge that referees make calls that can piss off players. In games where the stakes are high, players can easily lose it.
The clip you're about to see is definitely a demonstration of that. The player was at the blue line and he threw his stick at the referee like it was a missile of some sort. Watch :
Whatever call he made to have the player pissed off like this, this is an absolutely unacceptable behavior and he should be getting a long suspension.
