What merits an USC on the coach?

[kentref]

I'd like your opinions on what verbal outburst(s) gets a coach an unsportsmanlike conduct penalty. In other words, what does the coach have to say to cross the line?

I had one in a JV game today. Coach first yells to me, "Get your head in the game!" Then, a few seconds later, unloads with a, "you've already earned your pay with that _ _ _ _ call, etc."

Had he not verbalized it loud enough for half the stadium to hear then I might have let it slide.

So what does it take for the coach to cross your line?
