Wither: Verb. Become shrunken or wrinkled from age or disease.

Dear sweet Jesus, would you look at Victoria Beckham? Are abdominals supposed to wither like that? She looks like a balloon leftover from a party that just sits around for a few weeks until it becomes half-deflated and all shriveled looking. Or you know, a mummy that's been ripening for a century or two. Yes, that's exactly it. So uh, maybe someone should tell Posh she's about 100 years early for the Spice Girls: Walking Corpse Reunion Tour?
