You've seen hockey players brawl on the ice and beat each other with their sticks, but revenge licking is a new one.

The NHL has ordered Brad Marchand of the Boston Bruins to stop licking opponents. They say if he continues, he'll be fined or even suspended. Marchand's victims have compared the licking to spitting and say he should be penalized for it. Meanwhile, Marchand seems to find it hilarious, but has admitted that he should probably stop.

As you can see in these videos, Marchand's licks range from a tongue to the neck, to licks that start at the chin and go all the way up.
