What would you do?

[Lotto]

High school girl's varsity game. Extremely small gym. Home coach and crowd (no doubt following the spirit of the home coach) are quesitoning every call. Game very close. I'd T'd the coach with about 2 minutes left for coming after my partner on a foul call he made. (He claimed he was just yelling at his players, but I didn't believe him.) I make an out of bounds call on a home player with 22 seconds left in the game. A group of boys sitting behind the home bench, who have been particularly rowdy all game, start chanting loudly, in unison, "We got screwed! We got screwed!"

What do you do, if anything?
