Pranks with friends are all fun and games... until someone gets hurt, and it gets caught on film.
"Smack Cam," a new trend on the social video network Vine, started out as a joke between a handful of young friends. The idea -- to slap someone on the face and upload the footage online -- quickly took off and became a viral trend for teens.
One teen uses Axe Body Spray and a lighter to create a small fire in his hand, which he throws at a friend. Another video, which has been shared almost 7,000 times, shows a girl being hit in the back of the head with a gallon of orange juice.
Katie Baker wrote about the troubling new trend for Jezebel.com:
The [Smack Cam examples] I've seen remind me of Emily Bazelon's definition of bullying: "physical or verbal abuse, repeated over time, and involving a power imbalance. In other words, it's about one person with more social status lording it over another person, over and over again, to make him miserable."
