Nothing at all wrong with getting a tattoo/tattoo's. Just make sure you get them done by a competent artist who is actually good at his job, even if it's a piece of flash out of a book in the shop or on the wall.. if the artist is good then the tattoo will look good.
Tattoo's don't have to have a meaning, yes it's a common reason to get them but it's completely fine to get a without a meaning, you may think the design looks really nice and maybe you just get something you like.. it doesn't have to have a deep meaning to it.
I have at least 2 tattoo's that people could claim to be 'rebelious' but i'm faaaar from that, i'm easy going and really laid back, i got those 'rebelious' tattoo's because i liked the idea i came up for them. (the tattoo's in question are a bio-mech piece on the left side of my neck, and Sink and Swim on my knuckes/fingers) Also i like the idea of having many tattoo's on the body (pretty much covered) in the end i will be getting full arm sleeves (nearly there anyway) leg sleeves (and some on my thighs) the other side and back of my neck, a chest piece and most if not all of my back tattooed... that doesn't make me a bad person, it just means i have alot of creative idea's for tattoo's. To me, as an artist, tattoo's are an art form and the body is just another surface for art to be created on.
I will end here, because i have wrote enough as it is..and i get defensive of the subject of tattoo's and could go on all night XD
