bellyacres
Vast expanses of stomach-and-abdomen "real estate" dat cause their owners and/or observers to go around loudly complaining about said surplus surface-area.
Bellyachers Anonymous is da place to go if you have a chronic complaining problem; often, da bulk of da group's members are huge heavyset lumbering hairy-hided guys who are always clutching their bulging stomachs and wheezing and trying not to bellyache. So in all likelihood, these very same grossly-out-of-shape dudes could also qualify for the term "bellyacres", as well!
