Etymology

Origin of crusty

Middle English word dating back to 1350–1400; see origin at crust, -y 1

Explanation

The adjective crusty is good for describing something that is crisp on the outside, like a loaf of French bread. You can describe something with a crunchy outer layer and a softer inside as crusty, but you can also use the word to mean "crabby" or "ill-tempered." Your mean old neighbor who yells at kids to get off his lawn is crusty, for example. While the literal meaning is older, this "cranky or surly" meaning has been around since the 1500s. The root of both is the Latin crusta, "rind, crust, shell or bark."
