PSA: "Sack tapping" game may result in loss of testicles.

It's all fun and games until someone loses a testicle. From News.com.au:

A Minnesota teenager had to have his testicle amputated after being punched in the groin by a classmate.

KARE11.com said David Gibbons, 14, was changing classes in his Crosby high school when he was attacked by another student playing a game called "sack tapping".

David’s mother, Christy Gibbons, said it wasn't until hours later that they realised something was wrong.

"One o'clock in the morning he woke me up and told me he was in excruciating pain," she said.

David was taken to St Joseph's Hospital in Brainerd, Minnesota where surgeons removed his right testicle.

And David is not the only student who has suffered the consequences of the "sack tapping" game.

"It's just gotten way out of control," said Dr Scott Wheeler, a urologist in Brainerd, Minnesota who says he performs three to four surgeries a year on boys with ruptured testicles and other complications as a result of "sack tapping".

"All parents, you need to have this talk with your kids not to do it. It's lost its humour. It's not a game anymore. People get hurt," he added.
