fat cat

Meaning: A rich but usually lazy person.

Example: “The protesters blamed the fat cats on the board for the layoffs.”

Origin: American slang from the 1920s. The journalist Frank Kent used it in 1928 for wealthy men who gave large donations to political campaigns, and it has kept its sense of a rich, privileged and often complacent person. The comparison is to a well-fed, lazy house cat.
