What does a clown mean?

The clown is the super villain of DC Comics and Batman's sworn enemy. He made his debut in the first issue of Batman's one-line bound volume in April, 1940. His role was inspired by the smiling man in the novel The Smiling Man by the famous French writer victor hugo. After the discussion among bob kane, Bill Finger and Jerry Robinson, he finally positioned it as a whole. The clown playing cards in "The King" is Jerry Robinson's exclusive idea, and the clown is called "the most attractive super villain among beautiful women"
