The handle above the passenger-seat window that wary riders may often grab during the course of the ride, especially during particularly rough sections. A colorful word or two may often accompany a reach for the crap handle, if the driver is exceptionally terrible. Example: I like learning to drive with Clay so much better. Whenever I go out with Mom she grabs the old crap handle and tells me to slow down.
