Closely-Guarded-Explain

[firedoc]

The rule is that you may not hold or dribble the ball in the frontcourt when a defender has established a guarding position within 6 feet of you. This 5 second count continues even if the defenders switch off as long as at least 1 of them remains within 6 feet.

I don't think that there is a specific mechanic for this violation. The mechanic that I use is: whistle with the hand straight up with open hand indicating a violation, hold up 5 fingers and announce "closely guarded," then indicate the direction that the ball will now go and point to the appropriate spot for the throw-in.
