I like tattoos as long as they aren't horribly mismatched. A good (bad) example of this is a guy I saw that had Hitler's portrait tattooed on one arm, and Minnie Mouse on the other, along with dozens of other random things.
I think for a woman, getting F-holes (like on a violin/viola/cello) on the back is absolutely wonderful:
My favorite tattoo scheme would be a guy that used to work at our Borders. He had this Aztec theme going, with a patter going evenly around his neck and Quetzalcoatl earrings. Or my old art teacher (you would remember, Ence), who had something like Indian pottery designs all over his body. Things that make your body a unified work of art are awesome. One tattoo of something you love, or for a good reason is cool. Lots of random crap is just ugly.
That said, I'm getting a tattoo with one of my friends sometime this semester. Nothing big, just an alto clef; we're both violists, so we're getting the same thing:
He's planning on expanding his tattoos, but this is the only one I'm getting. I won't get tired of it, but I'm having trouble deciding where to put it. I need it in a place that can be both easily concealed and revealed.
Jam it back in, in the dark.
