“The process is called many things, ‘the unit’, ‘the duker’, ‘the shitter’, and ‘the groover’. The term ‘groover’ refers to the practice of using unimproved 20MM metal ammunition boxes to sit on while you did your business. The resulting grooves on your hinie sparked the name groover for the box. A modified toilet seat took care of that. Related to the grooving scene is placement, separation of function, hygiene, and courtesy.” (Solid Waste Management - Copyright © River Runners For Wilderness 2007-2010)
