Tattoo equals stupid.
Take your dumbest fashion idea, now make it permanent.
Yes, there are some good looking tattoos, though they are extremely rare.
These types of markings need some sort of cultural reference. Assuming you're a 21st century westerner, there's no way you'll come by that cultural context honestly. You aren't a sailor, or a native, or a norse warrior, or a Maori. At best you'll make some lame reference to these. At worst, you'll identify with the only real cultural context that ink and piercings have in our culture -- the loser, trailer park, dope/crack-head, drop out, criminal, ignorant loser. Might as well tattoo a photorealistic vagina on your forehead for all the good a tattoo will do you.
Yes, you can put it somewhere where it's easy to cover-up, but what's the point of the that?
Tattoos are expensive. Wanna make an impression young man? Go buy yourself a nice suit. That's an investment that will repay itself. A tattoo is just an expensive diversion that closes more doors than it opens.
