The term used for the consistency of some good weed. When you break up the buds it has a certain snap to it so that all the resin glands have melded into each other. Like breaking off a peice of the bud wouldn't crumble but stay together. Buds that have dried just right, so that it smokes evenly.
Dude, that bud was cruspy.
Break up some of that cruspy bud and lets get high.
