Tattoos don't have to have a particular meaning.
I think that when people see you have a tattoo they expect some long, grand answer about how much the tattoo means to you. They ask you what it means, (which by itself is still invasive), and get slightly offended or bothered when the answer is nothing, but rather you just liked it so you got it. They expect you to say how it was your grandma's favorite flower, in memorize of a friend, or it's a cultural, traditional tattoo. This doesn't always have to be the case. If it is, great, but if not, that's okay, too.
Tattoos can hold significant meaning. Tattoos can also be an animated piece of pizza or a sushi roll. It all boils down to how you feel about it. If you like it, great. If not, don't get it. Don't care what people think.
Tattoos that hold significant meaning can be amazing. They can be a reminder of hardships we've over come, a reminder of our loved one we miss dearly, or a reminder to ourselves of the future. Tattoos are permanent, after all, so why not get something we like? Why not get something that we'll love to stare at and take pride in having forever?
On the contrasting side, tattoos that don't hold a significance, per say, can still capture the memories, the moments, and the time spent getting the tattoo you like and having a great experience.
So stop judging people if they have a tattoo they got just because they liked it. Stop judging people who get flash tattoos. Stop judging people who walk in to the tattoo shop and get that random pineapple. Just because it's not your cup of tea, doesn't mean it's not theirs, so stop holding high expectations.
