A crooked or twisted shape, or something that is bent and misshapen; a Scottish/dialectal term.
From Scottish English, possibly related to 'cam' (crooked) and Gaelic influences, used in Northern British dialects to describe distorted shapes.
Scottish English preserved so many words for describing twisted and bent things—probably because living in rough, hilly terrain meant dealing with crooked wood, stones, and paths constantly.
