First there was the Dirk Nowitzki ass tat dude. It was the kind of tat that makes a huge splash on the Internet but then fades away because it's not seen unless Dirk Ass Tat dude wears a mankini to the beach. Enter Dirk Back Tat Bro. He's super Mavs fan - at least for the last couple years. Dedicated. Loves his German 7-footer. Loves being a world champion even more. Time to get some ink. Shockingly, the back and ass tat look nearly identical. Must be same artist. JUMP!
