Road-Rim 

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

Road Rim

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.

I gave him road rim while he was driving.

Rimrock Road 

A rimrock road is the process of the passenger sitting on the drivers face, so he may receive a rimjob A.K.A.: the act of orally stimulating the external anal sphincter to cause sexual arousal, whilst the car is in motion.

I picked up a hitchhiker and as her fee, i asked her for a rimrock road which she respectfully accepted, my asshole has never seen cleaner days.

The modern day "down with it like four flat tires". One is so hip and with it they are called "rimming the road".
