Yes, and high school officials call more phantom travels than any other level. We can always talk about what should have been called, but to call things that clearly were not violations is not right either and worse.

Apples and skateboards, IMO.
Let me change it slightly so it's more applicable.

A1 throws a pass to a wide open A2 in transition. A2 has a layup pending, all he has to do is catch the ball. Instead, the pass goes right through his legs and out of bounds. A1 is furious, and lights into A2 with a profanity laced tirade.

'You dumb-a$$! I've been putting up with your bullsh!t all year, and I'm f$cking sick of it!"

You going to let it go?

What about a fight between teammates?

The reason your example above doesn't work is because there's no rule against a player slapping himself. If you can show me in the rules where it says unsporting conduct must be directed towards an official or opponent in order to be penalized, I'll concede they're similar.

One might consider those game interrupters. :)
