Masturbation while driving an automobile.
Jimmy was bored and horny on that long, solo drive home from college, so he pulled out his dong and had a nice road whack.
Like Bovril Boulevard but for the working classes.
Alan: Ooh my Bovril B Road took a right bashing from the highways agency last.
A highway that gets a lot of salt put on it in the winter.
The county plow trucks are out spreading salt and making road jerky.
Road head, but for girls: the driver’s seat is reclined 180 degrees, the giver lies down and has their head on the seat towards the peddles. The woman props her left foot up and uses her other to control the peddles while effectively riding the other party’s face while driving
Guy: will you give me road head on our trip??
Girl: only if you give me road honey in return ;)
The act of pleasuring oneself while travelling in a car or similar vehicle
"You feel like road rubbing on the way home?"
I'm finna hit the road block
She didn't wanna make me a sandwich
