Our kids are marching off the cliff.
Roshambo!
I re-read the article and still couldn't find any indication that the victims were asking to be hit in the groin. The assailant might think it's a great game - the victim, not so much.
Our kids are being led off a cliff.
Why would any male volunteer for this? It happened to me playing sports by accident, and it’s a literally debilitating, sickening pain that takes half an hour to recover enough to even walk. Get hit hard enough and you’re laid out and under a doctor’s care for a week. It’s not fun, and it’s not funny.
That reduces my sympathy quite a few notches. Thin the herd.
