An incredibly smooth area that few people are going to see unless you let them? A great place for whatever tattoo you desire. The buttocks has a lot of skin is clearly visible, with few bumps that could mess up your design. If you have a specific design that you want more than anything and you are not sure if it will look good anywhere else, the buttocks is the way to go. This area is prone to sagging though, so if you needed an excuse to go to the gym, there you go.
