College hockey player absolutely destroys goalie, chaos ensues.

In hockey, few things are absolute no-nos. Hitting the goalie on purpose in a way designed to hurt him is a cardinal sin for anyone who played more than 20 mins of hockey in his life. 

University of Minnesota - Duluth's player Neal Pionk is seen here doing the worst thing you can do : ramming a goalie in his butterfly stance. 

The position is extremely vulnerable for the goalie's knees. It is unknown if the goalie Cam Johnson was injured on the sequence, but Pionk received a few ''love taps'' for his move. 

Don't do that, man.
