The world's worst Lyft passenger assaulted a driver and took off with his SUV after peeing in the back seat, police say.

An NYPD spokesperson told Gothamist that the driver picked up a group of passengers, including the alleged assailant, in Manhattan and began driving them to Brooklyn around 3 a.m. The driver dropped off the group, but one passenger refused to get out of the SUV and offered to pay the driver in cash to drop him off at 65 Roebling Street.

When the car was near the corner of Bushwick Avenue and Willoughby Avenue, the passenger began to pee in the backseat of the vehicle. The driver stopped the car and called the cops—but before they arrived, the passenger finished relieving himself, punched the driver in the head, and drove off with the car. Finally, something that's ruder to your driver than messily making out in the back seat.

Police later found the SUV parked on South 1st Street in Williamsburg, but no arrests have been made. The passenger is described as having brown hair, standing around 6 feet tall, and weighing 170 pounds.
