Etymology
Origin of kook
First recorded in 1955–60; perhaps alteration of cuckoo
Explanation
A kook is a nut or a weirdo — in other words, an eccentric person. Your favorite aunt might be a bit of a kook, with her crazy hair and wild outfits. The class clown in school is often a kook, saying nutty things in order to get attention, and you may think of the guy in your town who always holds a sign saying, "THE END IS NEAR" as a kook too. The word comes from kooky, "strange," probably stemming from cuckoo, which is a type of bird but also slang for "mad or insane person."
