Yin yang

[Tina]

Okay... Dont listen to anyone else because most of them are dumbasses. The spiral (Yin-Yang) is most commonly Good and Evil (White and Black), but it can be among other things as long at its opposing the other.

The other definition here claiming that yin yang refers to anus is correct, and older people in certain regions of the US know this very well. This site is for slang usages, not the formal dictionary definition which would refer to the Chinese symbol. When a person says something like, Wow, this store has widgets up the yin yang, it does not mean plethora. Rather, its a substitution for the word ass. And in a sexual context, yin yang does indeed refer to the anus. Taking it up the yin yang is probably the most used phrase, although its now somewhat antiquated, and it means taking it up the anus, or male/female part which is common to men and women, which is how the word was derived since the Chinese symbol represents the male/female balance.

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, and yang(male), to denote the anus in sexual contexts. Infrequently used.
