I have no idea why they do it, but I see that a lot around here, especially at college. And the thing that I've noticed is that most of the girls who go for the low-rider-and-thong look are a good 30 pounds overweight or more. I mean, being overweight like that is not necessarily bad- I know a number of women who are heavier than that who I find sexy as hell- but dressing to emphasize it is just plain horrid. Seeing these lipidinous wads poking out of belly shirts and overflowing waistbands like that is enough to make me want to petition for new legislation sometimes...

On the other hand, maybe they think it's like having extra breasts?...
