Crusty Demon 

Refrain from cleaning your asshole for two weeks. Then request a rim job from a girl.

"I gave her the best Crust Demon last night"

"I was planning on giving her a Crusty Demon however the diareah i had last night required me to wipe."

Demon's Crust 

What's left over after a demon orgy covers an entire room in bodily fluids.

Most specifically the layer of these fluids that dry up and cause most cloth to become brittle and stiff, on skin it's a semitransparent glaze.

Demon1: "Dude, what happened last night? I'm covered in something crunchy..."
Demon2: "HAH! Looks like you've got a full body coat of Demon's Crust."
