Long before Miley irrevocably shifted the national conversation in the direction of feverishly jiggling glutei, there were the Twerking Girls. This unabashedly trio of bootylicious women joyfully — but with hilariously straight faces — rapidly oscillated that which their mothers gifted unto them up and down the city. They shimmied through the Apple Store and all around Union Square. They headstood on cable cars and cafeteria tables, invaded laundromats and tiny GoCARS, stunned ’em on BART and at Macy’s. In the sight of God and 2Chainz, they twerked their way right down the veggie aisle at the Safeway. The hypnotically undulating hijinks of Cherry Red, Dollface, and Tastee were captured this summer in a viral video, “Twerking in San Francisco Prank” by the Simple Pickup crew (a trio of dudes made infamous by filming themselves aggressively hitting on unsuspecting women; this celebratory video proved there is a spark of good in everyone). At first watch, you can’t stop laughing at the befuddled, bewildered, or frozen faces of some of the people shocked by the Twerking Girls’ hypnotic undulations. But then a larger, deeper point takes over: damn, San Francisco’s gotten mighty uptight. Thank you, Twerking Girls and friends, for shaking some soul in the city’s face.
