Not using it any more.

[umpref]

I have found it to work very well. The verbage that goes along with it varies per the situation and/or my relationship with the coach. I never use the words "Not another word" when using the Stop Sign, because another word always follows. Usually "We are not going to talk about this anymore coach" is enough. I may follow with a "I heard you. Let's go", and I move on. If he continues, I give him the consequence.
