Its what you don't know.
You don't really know how to have fun in the cold.
You don't know how to really pronounce "out" and "about"
ootanaboot!
You don't know how to really wail on somebody and then go have a beer together and laugh about it.
done it. Minus the beer.
You don't know how to take the wheels off of the refs car while he is officiating your game.
Wanted to do something like that once... Punching in the face is the same, right?
You don't know how to put a bit of tape on your buddies skate blade when he isn't looking so he looks like a four year old when he steps on the ice for his next shift.
Tried, damn tape wouldn't stick.
You don't know how to really screw with the other teams head during adult league playoffs. (hint-"accidentally" walk into the wrong locker room and when they are yelling at you to get the eff out just turn and say "nice dick dude"). Messed them up badly and we ended up winning the league championship.
You have missed out on lots of fun!
