a slang used to refer to the perineum, the part of the body between the anus and genital organs, overlying the pubococcygeal muscle. This term supposedly originates from the fact that, "'Tain't your balls, and 'tain't your ass," "'tain't" being a contraction of "it" and "ain't", in this case, meaning "it is not."
SON: "Hey Dad, how come they call it a taint?"

FATHER: "Well son, 'cause 'tain't your balls, and 'tain't your ass."

SON: "Oh."
