I would probably just say something like “bouncer-like.” It’s vague but suggestive enough that you probably have a fairly accurate mental picture. But if you pressed me to be more specific I would say, from top to bottom:

1. Round-headed

2. Squinty-eyed

3. Puffy-cheeked

4. Thick-nicked

5. Broad-shouldered

6. Short-armed

7. Barrell-chested

8. Beer-bellied (slightly)

9. Wide-assed

10. Stout-legged

11. Wide-footed
