Pros: everyone who sees it will know you're an idiot and will know not to take you seriously.
Cons: everyone who sees it will know you're an idiot and will know not to take you seriously.
Even people who are huge fans of tattoos will tell you that the last thing you EVER want to tattoo on yourself is your lover's name, because a year or two from now, when you've moved on, it's not only going to make you look stupid, but it's going to make any girl you want to be with upset or angry. To do this is the very height of short-sightedness.
Pro: Show that she's important to you, a part of your life, she might possibly think it was romantic.
Cons: Why do you need it? .. you don't, If you were to break up..then what, if you want it removed in the future - it can cost quite a bit and is a lot of effort, awkward if you break up then want to date someone new.
I wouldn't recommend a name tattoo whatsoever, especially on your arm, if you're addiment of getting it, get it somewhere not so blatantly obvious like on your chest or ribs or something.
A better option would be something symbolic of her, something that represents her but when/if she leaves you then it's just a pretty tattoo that you like, or that can easily be covered up or turned into something else.
Man unless her name is like also your moms name or daughter or something like that where you can pass off her name as someone else don't get one. It always turns out bad. If you do have a good plan for a cover-up later. I don't know much about tattoos but I'm sure there is some way you can make it cover-up friendly for the next artist lol.
horrible idea I wouldn't recommend tattooing anyones name on yourself anything can happen and tat removal is expensive and painful so you'll be stuck with a constant reminder of how much you hate them if something goes wrong
