The act of licking a persons sphincter in a circular motion while they are driving a car. Best achieved if you put the car into cruise control.

While driving, the male or female puts cruise control, then proceeds to lift their butt of their seat. The passenger in the car then takes off the driver's pants and proceeds to give them a rim job while the car is moving.
On the way to the party, my girlfriend gave me the nicest road-rim of all time bro, it felt soo good
