If you want to pierce your eyebrow, it's your business. I really don't have a problem with it. In fact, on some people, many people, it can be very cute (read: Hannah N.).
If, Nordic guy, you're going to pierce your eyebrow, maybe--and this is just a recommendation--you could take the time to tweeze? Just a little? And most importantly, more important than anything, in fact, DON'T choose the green earring / hardware. Next to your bushy blond eyebrow, it just looks infected and makes me very uneasy to drink the coffee or eat the meal you've just made for me.
I'm just saying.
