Plump works for me.

This came about because a department came down looking for our new "bariatric" slipper. All slippers are different colors, and the xl and xxl are both beige, so the departments can't tell which one is for bariatric patients. I guess obese people have more health issues, and need a slipper with more traction. (The slippers are actually the ankle socks you get when you're in the hospital). Heaven forbid someone mistakenly puts and xl slipper on them and they fall and hurt themselves.
