I have a tattoo based on a nickname. In highschool I was "Fish" or "Fishy" but it also happens to be one of my hobbies - I love fish. I have a betta fish tattoo on my thigh. No one gets to see it unless I take off my pants (so it's very personal to me and only a select few get to see it)

I agree it needs to be very personal, and I also believe in tattoos that can be fully hidden - not all of the world is fully accepting of them yet. Also I suggest thinking about future weight gain/babies when you think about location!
