N. Often mistaken for slut
A woman whose vagina lives and thrives, solely, to fuck the male penis. Usually devouring all energy and life force within her subject. Thus, the subjects penis retracts, causing the Vagipyre to find a larger, more staminous, subject. Vagipyres often carry deadly diseases and should be avoided at all costs.
"Dude, your sister is such a Vagipyre, she slept with eight guys in one night!"
