The Virgin Mary's hymen 

That which was ripped wide open and torn asunder when the Messiah was born. In keeping with the belief of immaculate conception, Jesus Christ must have been the one to rip his own mother's hymen, and in a way pop his own mother's cherry. This can be used as an explanation for his odd behavior later in life.
Many christians celebrate the breaking of the Virgin Mary's hymen on the 25th of December every year.

The Virgin Mary's hymen got all torn and bloody, hahaha.

Virgin Mary Syndrome 

That horrible panic a girl gets when her period is late... even though she has never come close to having sex.

Jane: "Joan, I'm so worried! My period is late! What if I am miraculously pregnant?!"

Joan: "Sounds like Virgin Mary Syndrome."

Virgin Mary Syndrome 

An extremely attractive young evangelical who frustrates mankind by refusing to allow anyone to sample her fine genetic attributes. Whilst occasionly this condition can be cured by marriage, in general, such women will shamelessly parade both their physical magnificance and their moral superiority before all men in order to satisfy their relentless desire for universal recognition. Virgin Mary Syndrome is commonly abbreviated to VMS.

Matt: Hey babe, grab your coat love, you've pulled.

Joanna: Sorry Matthew (whilst stroking his arm and pitying his damnation), I'm not that kind of girl, but you're welcome to come to my prayer meeting tomorrow morning.

Matt: Goddamit Jo, Brad told me had Virgin Mary Syndrome. Anyway, so have you seen Candi around?

Virgin Mary Syndrome 

When a girl is completley convinced that she is pregnant despite there being no possible way that she is because she either hasn't had sex in weeks/months or is still a virgin.

"Is Sarah okay"
"Yeah, she is just having Virgin Mary syndrome."
"Does her boyfriend know?"

Virgin Mary Morning Sickness 

A nauseous feeling in the morning that occurs with a female virgin who is not on their period. Since they are not on their period, they cannot be sick due to period cramps. And since they have never had sex, they cannot have morning sickness due to pregnancy unless they are pregnant with the Christ.

My mother thought I was coming down with something, but it turned out to just be Virgin Mary Morning Sickness.

Not so virgin Mary

A girl who either has the name of Mary and is a slut, or one who tries to act like a virgin but everyone knows is a slut.

I saw a not so virgin Mary at church today. She should not have been there.
