Health experts have warned that hitting on the groin or the so-called sack tapping of a friend by schoolchildren can actually lead to serious injury.

David Gibbons of Minnesota has had a bad experience with sack tapping after he had to get his right testicle removed following a punch in the groin by his school mate. Gibbons’ mother, Christy agreed that this incident proved sack tapping is not a game, "I've seen the pain he was in. I've seen what he went through every day, and it just breaks my heart and I don't want any other child to have to go through this."
David is now moving to a different school district, while his old school is investigating the incident.
