a guy and a girl are alone in a truck where he is riding in the middle while she drives. Named after the first bozo we ever saw do it.
LeRoy: Hey Bryan, did you see Billy sitting in the middle seat while Michelle was driving her truck?

Bryan: Yeah, when it's the other way around we call that something else. Guess we'll call this "Riding Billy" now.
