look up any word, like trill:
when a Mormon woman living in Provo, UT allows guys to fuck her in the ass to save her vaginal "virginity" and maintain the "honor code."
Mormon girl: Okay, Andrew... but you can only put it in my butt. I'm saving myself for marriage.

Andrew: Oh come on!! Don't be such a Provo Butt Slut.
