Flash mobs at public places is perhaps one of the most interesting performance trends that has emerged in recent years. But not everyone is pleased with them.

In Kerala, a video showing an angry onlooker slapping a girl during a flash mob performance has gone viral. The incident occurred during the performance of a group of students dancing to Lean On by Major Lazer and DJ Snake at a bus stop in Payyannur district of Kerala.

A woman wearing a orange coloured saree comes forward and slaps one of the girls. The reason for her doing so isn't conclusive yet. While some reports claim the woman is the mother of the girl, other reports say that she was annoyed because of the traffic jam caused due to the performance.
