Don't escalate the volume of the conversation. On the other hand, when you've had enough, say so without shouting. "Coach, I've heard enough about my strike zone today."
One very effective technique I've seen applied without using it yet myself goes something like this:
Coach comes out to 1B Ump to argue safe/out call. On his way back, he says, in a normal voice, to 3B Ump something like: "Your partner sucks today and you ain't any better."
3B Ump:"You really think so?"
Coach (stops): "Yep."
3B Ump (normal voice, no gesture yet): "You, Sir, are ejected."
Coach now screams and throws fit. 3B Ump NOW makes the heave-ho gesture.
I thought it was clever, if not a little deceptive.
Strikes and outs!
