Green’s Dictionary of Slang

cooch n.

also cootch, cutchie
[abbr./euph. for cunt n. (1); note Online Dict. Playground Slang (2001): ‘This word raises all sorts of interesting possibilities since the old Welsh word “cwtch” (which has a similar pronunciation) is often used to mean a “place of comfort”. It makes me wonder if the word was carried to the States by Welsh immigrants then mutated and adopted by peoples who would have no idea of its origins’]
