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.
Example:
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.
