Try to get someone that is in charge to handle the situation. In many youth games, there are no game management people. You might just have the home coach responsible, but other than that you do not want to get into too much of a verbal contest with a fan. You are the only person that will lose in that battle. Mainly because they will might react in a way you do not like and accuse you of cursing at them or calling them names. Silence cannot be quoted.
