Interesting... I can't find anything in the NFHS rule book either.
At a game I had a few weeks ago, several students we using cow bells in the stands (the cows were
not attached). I told game management that the bells had to go and they took care of it.
There was no way that I was going to listen to that junk all game long!
Anyway, I'd be interested in anyone finds a direct or related rule reference...
The students were pretty funny - reminded me of how stupid I was in high school and college. They were mostly yelling at the other players (although they did use the old "Go back to Foot Locker" thing, which I always think is funny - one from my personal reportoire).
Anyway, they were yelling "YOU SUCK!" really loud at several of the other players, which is just really mean
So, when I was over on the sideline near them I said, "Guys, quit yelling you suck - say something else." Of course, they immediately begin yelling, "YOU STINK!!", "YOU SMELL!!"
