Chrust

The hardened/crusty layer that builds up on one's butthole after not maintaining cleanliness.

1. John's chrust was giving away a weird smell today on the bus.
2. I was going to eat Mary's ass, but I noticed her chrust and threw up on her.
3. Since I do not shower often, my mother recommends to use baby wipes after pooping so I do not form chrust.
