The anus. Yin in Chinese philosophy refers to feminine energy, while yang refers to masculine energy. The word has been incorporated into American slang to mean the male/female part. In effect, while males and females have different sexual organs, the anus is common to both sexes, thus the use of yin(female), and yang(male), to denote the anus in sexual contexts. Infrequently used.
(Mockingly) Gay Fred likes to take it up the ol' yin yang!
