Usually used in reference to an unattainable male celebrity, this is a title given to the one person who's every word, action, or look most quickly makes the speaker's vagina wet for their cock (or fingers/tongue/whatever). It is implied that the speaker is (or would like to be) a sub with this person as their Dom in a D/s relationship; as the Pope is the leader of the Catholic church, the speaker would like for this person to be the leader of their vagina.
A girl whose vagina is so huge it almost seems magical. She can fit umbrellas, cows, and half of "small town USA" in it- at the same time. When she sends naked pictures of herself she leaves her panties on so all of her "special belongings" don't fall out. Beware, if you choose to enter, you get a free gift with penetration... if you can find your way out. The gift that keeps on giving...
