A vagina that belongs to a very innocent girl, like that shit hasn't even been touched. No sexual thoughts have ever been considered down there.

A girl with a nun vagina has nobody going down there, she probably doesn't even check herself. In some cases, that shit could be crusty and even have cobwebs down there. A girl with a nun vagina is not rare at all. It could also be hairy, like I mean fucking velcro. They probably shampoo and even condition that shit. She probably doesn't even know the definition of truffle butter.
Sabs: "Hey bro, would you ever smash that?"
Matt: "Nah fam, she's got a nun vagina, that shit probably crustier than the Krusty Krab!"

Get the Nun Vagina mug.
Extremely lonely; untouched; sad and forlorn; abstinent but not necessarily by choice (ironically, unlike a nun's actual vagina).
Luke hasn't had a date in months. Not sure if it's his work schedule or what. He's lonelier than a nun's vagina.
