They showed a guy on the jumbotron at the game Saturday with the flaming brand on his bicept. I'm not big on the flaming brand for the most part, but it looked good as a tattoo. I really don't have a desire to get a tattoo myself, but if it's your thing, go for it.
My brother has several tats ... all tigers. I have no idea why.
Now ... If you want something big and extreme, you could do like my brother-in-law: he has a tat of Gandalf fighting the Balrog ... from his chest to his back! He also has a remake of a Salvador Dali painting on one of his sides, as well as a Buddah head and a koi (along with other oriental imagery) on his forearm, which he hopes to make a full sleeve someday.
