dried-up anal and vagininal secretions around a woman's cunt, as a result of her not washing her pussy. usually, the uglier or older the woman is, the thicker her crust is. crust has a tendency to smell like fish mixed with anal juices, and some canned tuna companies do not actually can tuna, but actually crust scraped from fat, ugly, 40 year old women.
