Explanation

  • A bad person; someone who is dishonest, untrustworthy, or generally causes trouble.

Origin

  • Comes from the literal experience of cracking open an egg only to find it rotten.
  • A rotten egg looks normal on the outside but is unpleasant and useless (or worse) on the inside.
  • The term transfers this idea of hidden unpleasantness or corruption to a person's character.
