“Do you think my tattoo is cool?” No, I don’t. There are no cool tattoos. “Check out my sleeve!” Oh god ew.
Tattoos themselves are stupid. Doubly so if it’s some media IP. “I put Batman on my body!” “Look at this image of Goku on my calf!” I can’t think of many things I’d want to do less than that.
There are a few narrow exceptions. Chances are yours isn’t one of them.
If you personally like tattoos, fine. I’m not saying nobody should get tattoos because I don’t like them. I’m stating my opinion that tattoos are stupid, and I am stating it here because it is probably not a popular opinion.
There are loads of bad art tattoos out there by third rate tattoo artists.
I would say fewer than 1/1000 tattoos make me stop and think “oh that’s beautiful.” Most I see are so ugly I feel bad for the person, knowing I would regret it if I had their tattoos.
