Twerking Flash Mob Takes Over San Francisco (VIDEO) (EXPLICIT LANGUAGE)

They're at your laundromat and in the produce aisle. They're on the subway and at the food court in the mall.

They're the twerking flash mob and they've taken over San Francisco.

A new video by Simple Pickup shows a trio of ladies twerking on cable cars and with a homeless man, twerking in Union Square in front of a baby and -- our personal favorite -- twerking to the gentle sounds of a classic Chinese orchestra in Chinatown.

The video contains only a brilliantly simple description: black girls twerk in front of confused white people.

Who are these twerkers? Who knows? Who cares? We can't get enough of them.
