That's a specific type of unsportsmanlike conduct, but it's too narrow for the clue. The clue mentions speaking, which is also a type of unsportsmanlike conduct (taunting).
The comment refers to the personal foul question, for which the clue is "An illegal, flagrant foul considered risky to the health of another player". To me unnecessary roughness would fit under that definition.
like I've never heard a ref call someone for running into the kicker
