Origin
An allusion to an egg that has become rotten, first appearing in the mid-19th century as a metaphor for a person whose character is found to be similarly spoiled. The comparison rests upon the fact that the exterior of an egg remains deceptively clean while the interior has grown sulfurous and quite unusable. It is a social observation of the most practical sort: one does not typically discover the nature of the specimen until the shell has been cracked.
