Slang and vulgar term for female genitalia, literally 'flesh folds'. Used in explicit or crude contexts.
fleshy fold
Rare literal meaning: a fold or pleat of flesh. Not commonly used outside anatomical or descriptive contexts.

I saw the word 肉襞 in an anatomy reference, but it's not common.
Standard kanji spelling; 襞 is a non-jōyō kanji meaning 'fold' or 'pleat'.
Mixed kanji-katakana spelling; the katakana ヒダ may soften the visual impact or aid readability.
Compound of 肉 (niku, 'flesh') and 襞 (hida, 'fold, pleat'). The reading ひだ for 襞 is standard. The slang sense derives from the visual resemblance.
