To reverse direction in an automobile by entering an intersection, veering right, and then tracing a path in the shape of an incandescent lightbulb, so as to result in the automobile re-entering the same street from which it originally entered the intersection, but now traveling in the opposite direction.
Man, we took a wrong turn, we're heading away from the strip club. Loop a bulb at this intersection - my girlfriend's on in ten minutes!
