So, this is totally a conversation starter. And I'm an introvert. I don't always like talking to people. So there will be many times in the future when someone asks me what my arm says and I will not feel like talking about it.
I am tempted to shrug and say, oh, it probably says 'pork bun,' which is a deliberate deception. It allows people to think that I don't know what it means and I feel kind of bad about not knowing. And it somehow feels like less of a lie than saying it means love and serenity or something. Or maybe it's that if I'm going to present myself as a person who was misguided enough to get a tattoo that didn't mean anything, at least I'm presenting myself as someone who knows better now. It makes me someone who made a mistake, but that's way better than being someone who blithely thinks it's a great idea.
I might be able to say something like, it's a long story. Which isn't exactly an answer to the question they asked, but might deter further questions. It means, if I tell you, I'll have to explain, and it's a long story that I don't feel like getting into. Which is, actually, exactly right. If it works. We'll see.
