hobbledehoy (n.) Look up hobbledehoy at Dictionary.com
"clumsy or awkward youth," 1530s, of uncertain origin and the subject of much discussion. Suspicion has focused on French or Anglo-French, but no appropriate word has been found there. First element is probably hob in its sense of "clown, prankster" (see hobgoblin), the second element perhaps is Middle French de haye "worthless, untamed, wild," literally "of the hedge."
