The ones with flower patterns that Deco 20 posted were really cool. I've never really been sure what I think about tattoos. I like them if they're cool.
But those generic barbed wire and tribal patterns around the bicep are cringeworthy to me. Tramp stamps, too. I like The Rock's big one, but it would just look silly on anyone who's not as huge as he is, or not as Samoan as he is.
If you're going to get ink poked into your skin, you might as well choose something that means something to you, not just do the same tribal pattern ring you saw on the bulky guy in the gym.
