Taint (slang)

Taint is a term used to refer to the perineum (the region of the human body between the testicles or vagina and the anus). This term has no basis in medical terminology and is most often considered lewd and mildly obscene. The word taint is derived from the combination of the words "it" and "ain’t" run together to form the portmanteau "taint." The joke commonly being: "It ain't your balls (or pussy) and it ain't your ass." Despite its dubious origins, the term taint has become relevant to pop culture, having been used by several television programs and stand up comedians. Such programs include SNL where Horatio Sanz played a man with no taint in a sketch with Conan O'Brien.
