Violation in Basketball game

Just want to share some information on Referee's sign during foul.
I found it as an interesting as I've been wondering for so many time, what the !@%6 is that referee saying.
But after reading the FIBA rules & regulation book, now i understand the meaning..haha..
It is funny watching and trying to interpret the meaning of the sign in the the first place.
I HAVE been naive, u know..but, not as blurr now..=)
Thansk to FIBA..
