Stopping the game and go to a parent and talk to them is not advisable. In some cases it only makes the situation worse and look like a comedy or drama.
What would yo do if some nut will say OK I'll do it? Or, who knows what else might happen. There is an established procedure when, in any case with a parent being out of line, you go to coach and ask coach to handle his/her parent(s) and if coach refuses then the game is over. But, imagine this very unpleasant situation, and the referee is 13-16 years old.
