adjective (British informal) stark naked
origin* "naked": British slang, from 1923, combining (like a popular etymology) two meanings of stark (“strong, utterly; barren”) with stark naked, which is from Old English steort (“tail”), referring to the tail-end (as in butt-naked). * "crazy": stark (“shortening of stark raving mad”) + -ers
