You've skewed the poll so I haven't voted.
I wanted to get a tattoo- a quaver on my hand a year ago- but I realised it wasn't very original. Plus my parents didn't want me to get one until I was 16, plus it was expensive and finding a reputable (clean, safe, professional) place to do it for me underage would be difficult. This sounds silly, but I also was worried about it going on and my hand being damaged, too. I'm a bit sensitive about my hands! And it would be just like me to have an allergic reaction.
I don't think they're particularly classy at all- but if they're subtle and plain black and small, they don't necessarily have to look common. If it's red and blue and messy and massive, then I'll write you off as common. Also if you have a name tattoo, especially if it's your kid's name...just tacky.
If I were to get one in the future, it would be somewhere like the palm of my hand or inside my arm. I wouldn't do anything big or anything like a quote or phrase, because you go through phases and I might turn on the quote the next year or week or day. Maybe 'bagism' for a joke.
