That kid who's had a little too much candy and is bouncing off the walls? Just call him rumbustious, an old word meaning noisy and undisciplined.

If you want to talk about someone who is unruly or just plain out of control, it's good to use an unruly word. In easygoing American English, we might refer to a rambunctious child, but before rambunctious there was rumbustious. That playful adjective goes all the way back to the late 18th century and still occasionally gets hauled out for comic effect, though using rambunctious will get you fewer odd looks.
