Etymology: "Nad" is a clipping of "gonad," the anatomical term for a sex gland, which in turn comes from the New Latin "gonas," itself drawn from Greek "gonos," meaning "offspring" or "seed." The full word is a learned scientific coinage built on that Greek root, not something from ancient Rome or Greece in its present form. The shortened form took on a slangy life of its own. Clipping is the process of trimming a longer word down to a shorter, more casual form, and "gonad" lost its final syllable in just this way. The result is a word that sounds informal and blunt, which is part of why it reads as slang rather than as clinical vocabulary.
