yelling during a pitch in slowpitch SB

How about a twist on this? Had a men's slow pitch tournament a couple years back where the pitcher chanted before the release. Of course, this guy was a Winnebago Sioux and did one of their chants while setting himself up before the pitch. He stopped the chant just as he was releasing the ball. He held the ball and glove up above his head, as if showing it to the gods or something. Didn't even look at the batter. Next thing I know, chanting stopped and the pitch was on its way. This was USSSA of course. Had the opposing manager in my face right on the first time he did it. I watched and watched. Couldn't find anything illegal about his delivery, etc. Told my UIC about it. He had the look on his face like I was a candidate for the looney bin or something. Interesting tournament that was.
