Worldstar Moment: Woman Attacks Man on NYC Subway & Gets Slapped!

Over the weekend another classic Worldstar moment went viral. The footage shows a group of young girls riding the F train on the NYC subway. One girl is making jokes about a passenger. What appears to be a small roast session quickly turns left when the young woman puts her hands on the passenger. Hit the flip to see the "Slap Felt Round the World." 

Do you think the slap was justified?
