adjective. ['ˈpɔntʃi'] having a large belly.
1. Adjective If you walk around all day not thinking about your posture or abdominal definition, your muscles stretch out over a paunchy stomach, so you look puffy rather than defined. 2. Noun, singular or mass You might think a weak chest, wimpy arms or a paunchy core would keep you from effectively doing push-ups, but you'd never suspect your elbows would be the body part to give you grief.
