Never heard of this call before
 

USA Hockey Junior rules in use:

In a game last night a player got called elbowing, then also got called for: Abuse of Officials.

Is this like a Unspostmanlike Conduct?

The player got hit with a 2-min. Minor for the elbowing, & a 10-min. Misconduct & 10-min. Game misconduct for the Abuse of Officials.

I've seen it called before. Yes, it's basically when a player/coach argues with or berates an official in an over-the-top manor. Buh-bye!

I figured that was the meaning behind the call, just with all I've read rule wise, it's a call I am not familiar with.

For clarification purposes, the signal used would be the USC signal correct?

The USC is for a minor penalty.

Both hands on the hips is the signal for the 10 minute misconduct.

No signal for Game Misconduct.
