i go to twerk

Have u ever tried twerking?  Maybe i'm doing it wrong but is it supposed to be ultra-painful? How do u unhinge your butt from your lower back like that and then flap it?   Anyway, um, "thanks" to Pinky for this. EmbarrASSed to say how many times ive watched. Ay yi yi. The one on the car hood?  As my old neighbor Mrs. Doyle used to say, "Well, Good Lord."
Still no tour or shows or anything...2busy dealing with unexpected guest.
