Moonbat is a pejorative political epithet used in United States politics, referring to liberals, progressives, or leftists.
Examples. 1  Sci-Fi writer Robert A. Heinlein first used the term moonbat in his short story Space Jockey. 2  I agree with westsideguy, moonbat is appropriately named if he/she thinks bringing in someone inexperienced to be the CFO of a bank is a good idea. 3  You could always toss in moonbat for effect though.
