GuyRule #558.0: Stick work
When playing pick-up hockey at the local rink, it is perfectly acceptable to slash, cross-check or spear your friends in a playful manner. If they get pissed off, you just tell them to grow some god damned testicles and play on. Never do it to someone you don't know, and if someone you don't know does it to you, it's time to drop the gloves.
Attempting to injure with the stick is strictly for Europeans and little neutered girly men. If you want to injure someone, pull his jersey over his head and nail him a couple of times. -Murph
Good hockey rule. -WP
