Unsportsmanlike Conduct --- Do you need to stop the action immediately?

I tried posting this on another forum, but didn't get an answer....

Dear Experienced refs.....

Luckily, this has not happened to me, but this scenario came to my head and I was wondering what would be the proper procedure on how to signal and call the following...

Wrestler A takes Wrester B to his back.
Wrestler B swears loudly.

Obviously (at least I hope...I couldn't find anything in the rule book)..this would be a delayed UCM (Unsportsmanlike Conduct -- Match point), and you would award this at the next stoppage or break in action

My question is....How do you signal this?!?! Normally, on UCM, the action is blown dead and all action is ceased.

My guess would be......use arm signal for UC [would this be vocalized as well?], go back to counting backs, and then wait for a stop in action to award the UCM followed by the NF?

If I'm completely wrong, feel free to chime in...I don't think you would stop the action, even though, in all other situations that I think of, UCM is an automatic stoppage, but I could be wrong there too.
