Mainly a sex act performed as a favour to men who drive convertible drop top coupés by women who want to get a ride with the top down. The man rolls down the hard top roof of the car and proceeds to place his mouth and nose in between the woman´s exposed breasts, while rocking his head side to side very rapidly while making a , lip-vibrating "brrr" sound. The vibrations stimulates the nerves around the nipples making them rock hard and is usually an invitation for the woman to straddle him for sex inside the car.
