A term for a woman with a body similar to the women painted by the artist Peter Paul Rubens. His painting called "Judgment of Paris" is a good example. The word has nothing at all to do with Ruben Studdard as it was in use long before American Idol existed. The women of Rubens' paintings typically had hourglass figures and were chubby, but not obese.
I like rubenesque women because they have big butts.
