Intentional or excessive intentional

[BillyMac]

An intentional foul is a personal or technical foul which neutralizes
an opponent's obvious advantageous position. Contact away from the ball or
when not making a legitimate attempt to play the ball or a player, specifically
designed to stop or keep the clock from starting, shall be intentional. Intentional
fouls may or may not be premeditated and are not based solely on the severity of
the act. A foul also shall be ruled intentional if while playing the ball a player
causes excessive contact with an opponent.

I don't believe that the NFHS has a "hard foul" intentional foul signal. I believe that only the NCAA-M have such a signal. However, my high school board has been taught this "hard foul" signal for several years.
