Japanese 干物女 (Himono-onna)(noun) A woman with little to no interest in relationships, and that prefers to stay at home lazying around; especially when showing a social face while outside.

A term translated literally as "dried-fish woman". Popularized by a recent anime, Himouto Umaru-Chan (where "Himouto" is a portmanteau between this word and "Imouto", a.k.a. "younger sister").
