It's been a banner week for horny dudes rubbing one out in public. Today, we have yet another video courtesy of Gothamist. This one shows a man who appears to be furiously masturbating in the driver's seat of a van parked on a street corner in Williamsburg. The witness who took the video this morning tells Gothamist, "I didn't stick around to catch him finish, but when I left my apartment he was still in the car, digging into a bag of Popchips with the same hand." Nice.
