To masturbate all over your partners face, unleashing an obscene amount of cum, which covers their entire face, especially their eyes. Then, your partner doesn't wash off the layer of jizz in time, letting the spunk harden over their entire face, very similar to the coverage of an unbaked pie crust in a pie tin.
"Hey babe! Can you get me some soap and a brillow pad? You pie crusted my face, and now I can't see."

Someone that is fun to hang out with but always is flaking when you are trying to hang out. It is often someone that is short.
Damn Madi is such a pie crust, she said she had to take a bath and take a nap instead of hanging out.

The filthy, diseased, nasty layer of scum covering a pussy rank with more STDs than you can name. Just looking at it makes dicks shrivel back into their owners for fear of catching the foul stuff. So nasty, not even the crabs like being there.
"Man, I was about to fuck this bitch, but man when she pulled off her panties.. the Pie Crust on that was so nasty I puked."

When a girl, no matter what size, wears pants that are way too tight. Their sides spill out, looking like pie crust.
