The act of simultaneously smoking marijuana, blasting music, and driving on remote roads. This is usually a group activity.
A good time to road bowl is when you get off a stressful day at work, and go and pick up some friends. One of them happens to have some marijuana, the other one has a pipe. So you drive up some old logging road, turn on the music loud, light up and pass to the left.
