what kind of comments/arguing from a coach constitute a technical foul?

"Do you get paid for this? If not, tell them you'll coach their team and they can take the abuse."

Hi Jimgolf,
We get paid $10 a game and sometimes I feel like paying someone else the $10 to take my place. We are shorthanded and if I don't do it, we'd only have one ref and I don't want him/her to have to call the game alone...
