A person that doesn't wash or someone that is socially crusty. Imagine a middle school boy that hasn't washed his hair since he was born. However, Someone that does wash can still be crusty. For instance, if they have a general disregard for social interaction you may get a feeling of crust coming from their personality. Therefore a crusty person can be physically crusty or mentally crusty. Crust is something that is foul and makes you frown. Just as an unhygienic pre-teen with crocks, a Hawaiian short sleeve button down and greasy hair makes someone frown.
Hey man did you see that guy?
Yeah man he was so crusty. He was a crusty person
Yeah man that guy was so crusty. Lets leave.
Yeah man he was so crusty. He was a crusty person
Yeah man that guy was so crusty. Lets leave.
