4. (US, slang) A small portable toilet often used on multiday river trips in protected wilderness areas, so named because the original versions were metal boxes whose rims left a groove in the skin of the user.Examples: "During an early river trip back in the 1970s, shortly after this system was developed, the toilet seat was accidentally left behind, the rims of the riser left telltale indentations on everyone's bums, and the box got a nickname: the groover. (Some guides also call it the duker or the unit.)"; "On the river, the matter of poop is taken care of by a "groover." Nothing special, the groover is a toilet seat set atop a military-surplus ammunition can with a special liner. So named for the days before rafters discovered they could place a toilet seat atop the ammo can and instead sat on the edges of the box, leaving grooves on their hindquarters—the groover is an effective, and enjoyable, way to crap in the woods. Some referred to the toilet as the "groover" in honor of the old days when there had been no toilet seat. Instead people would sit directly on the top of the ammo can, leaving telltale grooves in their skin"USslang
