A term that can be used to describe a cutely small, fat kid who appears as round as is tall. They look like you could turn them onto their bellies and bounce them up and down. It is often used as a schoolyard insult amongst young children.
"Ahhhhhh, he's a little bouncy ball. Look at him eating that ice cream while it drips all over his face! How strangely cute!"
