Your getting a tattoo man, it has to be something with a lot of meaning for you otherwise your going to regret it 20 years from now. Don't ask for ideas unless it's help designing a tattoo you already KNOW you want. Getting flash off the wall of a tattoo parlor is for tools (case in point, I overheard this kid talking about a star wars lego character he had tattooed on his arm "everybody asks me why I got it and if it has some meaning to me, haha no, I just got it cause it was fucking funny"). Getting a tattoo of something that means something to you is the only respectable way to do it.
