Instagram is our second favorite guilty pleasure. Women taking pictures of their own booties is our first favorite. We love that society has made it okay to pair these two together. It's a win, win!

Admittedly, it's time consuming to keep up with all the posted butt pics in real time. Thankfully, there is now a Twitter account dedicated to posting the best butts of Instagram in one simple Twitter feed.

The content is all user-submitted, so if you (or someone you know) happens to have an award-winning backside, you should consider submitting a pic. Here are some of our favorites.
