When to over-rule?

What is this "on the floor" stuff?
We all know that the act of shooting can start and even end with the player never leaving the floor. Look at how most players shoot free throws: they don't jump!
My point is that I cringe when I hear an official indicate that it is not a shooting foul by yelling, "ON THE FLOOR!"

I would suggest saying "No Shot." or "Before the shot." That is my mechanic.

Yes, I know that is what we all mean, but the choice of words is terrible.
