Bamboozle
Two circumstances have induced me to turn to bamboozle. First, I am constantly asked about its origin and have to confess my ignorance (with the disclaimer: “No one knows where it came from”; my acquaintances seldom understand this statement, for I have a reputation to live up to and am expected to provide final answers about the derivation of all words). Second, the Internet recycles the same meager information at our disposal again and again (I am not the only recipient of the fateful question). Since the etymology of bamboozle is guesswork from beginning to end, it matters little how often the uninspiring truth is repeated. Below I will say what little I can about the verb.
