Teens across America are enjoying a new kind of sport we can tentatively call, Shove This Baseball Bat Up That Homeless Man’s Butt game. And in some states, teenage kids add to the basic mechanics with innovations, such as making some homeless person eat his own barbecue grill.

Criminologists call these wilding sprees “sport killing,” — largely middle-class teens, with no criminal records, assaulting the homeless with bats, golf clubs, paintball guns.Some teens have even taped themselves in the act. Others have said they were inspired by “Bumfights,” a video series created in 2002 and sold on the Web that features homeless people pummeling each other for the promise of a few bucks.

A segment called “Bum Hunter,” hosted by a Crocodile Hunter-like actor wearing a safari outfit, shows him “tagging” homeless people by pouncing on them and binding their wrists.
