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...

Yeah, I've heard she has a Mary Poppins Vagina.

This occurs when a male collects a large quantity of his own ejaculate in one large container (the Mary Poppins Bag). A common use of the Mary Poppins Bag is to be tossed into an unexpecting female during their gynecology appointment - exploding on impact.

A "Cli" is when you tuck your man tackle out the back of your legs, put your knees together and it looks as though you are a Vagina man.
In 1978, a young lad from Invercargill (Peter Evans), while visiting students in Dunedin, took this a step further. He did a Cli while standing on the dining table at a party, while holding an open umbrella, then set fire to his pubic hair and jumped off the table, thus producing the first "Mary Poppins Flaming Cli".
