thin waists. If they are weight proportional, they will be labeled as athletic by the hobbyist that wrote their profile (normally the guy that does the first review). If all subsequent reviewers agree and call her athletic, then you should take a chance on her. There is an occasional woman that has wide hips, is athletic and has a flat behind, but those women are rare to find in that category, the overwhelming majority of women in that category have behinds to die for. In all cases, whether you like thin women that have large behinds or heavy women that have nice, large behinds, I suggest that you look for a woman whose hips size is at least 10 greater than her waist size, women with those deltas have the pleasing hourglass figure that makes the large behind even more appealing.
