“Nimrod” is a funny case. In the Bible, Nimrod is a king and a mighty hunter. In Looney Toons, Elmer Fudd, a decidedly not-mighty hunter, is sarcastically dubbed “Nimrod”, and so the connotation is reversed for those of us who are first exposed to the name as a sarcastic jibe from Bugs Bunny rather than the name of a Biblical figure.
