An overweight older child who is not quite obese, but certainly getting there.
Also has fat mostly developed in cheeks (buttock and facial) and chest area. This fat is usually flabbier than that of an actually obese child, and therefore the chubber jiggles a lot when it moves (even when talking), and therefore becomes the primary target of insults and cruel mockery among the neighborhood children.
That boy over there is having a tough time running around the bases. Oh, I wish his parents would buy him looser clothes or put him on a diet. It must be so embarrassing to be such a chubber.
