Certainly. And I'm getting my first in couple of months, as I got a gift certificate to a tattoo shop. I've always wanted tattoos and I've had my first ideas, that I'll probably execute too, about 8 years ago.
Tribal-style tattoos, chinese signs, bar codes (a lot of tattooists will straight-up disagree to even do those), dragons, butterflies, skulls, pentagrams... I won't be getting anything that unoriginal though. Neither anything related to a game/band or a commercial brand. That's for sure.
I have few good ideas, but I've not yet settled what I'm getting first. Also if and how I'd join them.
