Get the background propmug. The background check is preformed while hitting it doggystyle. You take your right thump and insert it into her ass. Be sure to wiggle it around and get it nice and deep. When you remove your thumb it should have a good amount of poo on it. Now take your right thumb and put a poopy thumb print on her ass cheek. Similar to a live scan, DROS, or background check.
