MIAMI - A new craze among Florida teenagers is causing concern among parents.
Cellphone video shows students crowded in a circle to watch a "slapping game," which consists of students hitting each other across the face.
The recorded video happened inside the cafeteria at a Miami high school.
The video also shows two school security guards who were present did nothing to stop the game.
School officials said they're investigating the matter.
