Steatopygia (yes, it's Greek for "fat-arse") is an anatomical feature known to anthropologists. The San people of southern Africa, whose traditional diet was low-fat, are noted for it; women store fat in their butts. It's very practical if you are a hunter-gatherer (well, since it's characteristic of the women, maybe just a gatherer)in the Kalihari, but for those not used to it it is rather startling at first. These ladies are pretty slender otherwise. In modern America, there are a lot of fat-asses, male and female, because we eat junk food and watch TV; but the rest of them is usually pretty big too. I heard of one of them that she read that Cher had a tattoo on her rump and wanted one there too, but gave up on the idea when she couldn't find a muralist.
