Crusty Crayola Crayon 

CCC. Crusty Crayola Crayon. A Crusty Crayola Crayon is someone who is well, crusty. Someone who is just down right gross. That one crayon no one wants because it's broken, used, dull, CRUSTY, paperless. The number one heartbreaking insult. - Dadalynn

"Ew she's such a crusty Crayola Crayon."
