OUCH !

Gone are the days when bullies merely gave wedgies. The newest fad in schoolyard violence? A quick slap to the testicles.

In the game of "sack tapping" or "ball tapping," as it is called, a boy will try to slap or flick the groin of another boy to inflict discomfort or pain.

The "game" has gotten out of hand, however, according to Dr. Scott Wheeler, a pediatric urologist in Minnesota.

In recent years he's seen an increasing number of young boys coming in with serious damage to the testicles because of a "tap" that hit too hard.

"For some reason, [this game] is popular," Wheeler says. "It's not just bullies, it's kids doing it to their friends. It's rare that bullies target the testicles, they just beat up people."
