The foul remnants of a drool-ridden sleep, or the substance located at the medial corner of the eye. Morning Crust can be found dotted around your lips, chin or cheeks after waking up from a good to excellent sleep or nap. Morning crust can also be discovered in the eyes, a small white build up of salt and water from your tear ducts can develop, thus leaving you with "Crusty eyes."
