a word used to describe someone who is extremely bitchy. usually after not getting pussy at a party or after having a series of bad events that comes their way. a person who does not like the word crusty is usually someone that the word crusty defines to the point of perfection. In order to rid of crust, one must do one of the following. Drink beer. Get a nut. Eat an Uncrustable. Or pack a monstrous lip.
