A lubrication rhino is a large, pointed, metal device that leaks lube. It has many sharp points, and is meant to go up a males arse. The product was discontinued in 1937 as reports came in of it causing anal lesions.
I got my hands on one of those old ass lubrication rhinos yesterday, and you were right! It does cause anal lesions.
