Indiscriminant nose-picking in a very deep fashion involving one or two fingers. Often seen at a stoplight on the car next to you. Sometimes followed by a sniffing of the fingers if productive, and/or rolling the residue with the index finger and thumb and flicking it either on the floorboard of the car or out the window.
Jared, check out that guy in the car next to us digging for gold. Dude, that is an Alabama Brain Massage if I've ever seen one!
