What merits an USC on the coach?

If a coach is going nuts on a call, I let him rant and show to the world how stupid he looks and sounds. If he's on the field, and gets off, he gets warned assuming nothing personal comes out, or there isn't language. But then he gets a reminder that if he does it again, he'll get flagged, and that it won't take much for me to do that. I know I cut too much slack, but it usually works because I remind them I'm being kind when I don't have to.

Not sure if a coach is berating a specific official that someone else should throw a flag, again short of language or something like that. In other words, if he's going after a WH, then the WH should throw the flag.
