That boys & girls is what we call a “blarge”. Back official called them fir a block & center official actually correctly called us for a charge. Thus a double foul—one one each team and the ball goes back to point if interruption, which means where it was, and we had it.
Really no different than if you call a double foul on two guys pushing each other in the post, they won’t quit, so you have to call a foul on each player.
But here you want one on one or the other and if the officials will lay off their preliminary signals, they can come together on a double whistle and just make one foul call
