high pitch scream in shooters face a "T"

[Oz Referee]

I would have warned the player (and coach) the first time it happened, the second time it would have been a T.

Mick as far as FIBA rules go - this is covered under the concept of "baiting" a player, I would imagine that you could also justify calling a T under the concept of unsportsmanlike conduct. Regardless, this behavious clearly has no place on a basketball court - if sreaming is the best defense you've got...take up table tennis!
