n. Word used to describe a birth defect in which a woman has more than one vagina. The actual term for the condition is Polyginastic Malfromic Syndrome, abbreviated P.M.S.

Women with this condition have been known to have as many as four vaginas, and the condition is typically lethal unless operated upon. All of the vaginas have the same functioning parts of a vagina, so a women could potentially be having 4 orgasms, periods, and babies at a time.

Though survival is typically rare, those who make it have been seen in porn movies, such as Back Door Sluts 9, and Aleta Takes it from Four Guys.
