Crotchball

So there I was, reading Eric D. Snider’s Snide Remarks column, when I came across this:

“My dad and Christopher also play a game called crotchball. They sit on the floor at opposite ends of the family room, about 18 feet apart, with their legs spread. Then they take turns throwing a foam rubber Nerf ball at one another as hard as they can. Players are not allowed to move to get out of the way. The goal is to hit the other person in the groin.”

But there’s more:

“The best part about crotchball is the noises my dad makes, not in response to being hit, but in anticipation that he’s about to be hit. This is a man in his 50s who has held several important church callings.”

I don’t know what a Nerf ball is. Is it anything like a cricket ball?
