A term for a child. It's used to describe a kid that's goofy or unruly or mean or sweet, you know?--it's all of the above! It's a great way to get a child to laugh...if they're 4 years old, at least.
(to child) "You are such a Piggleworm!" in a friendly, mean, sarcastic, or giggly voice, any of them!
