The 18-year-old boy, from Lorenskog in Norway, told local newspaper Romerikes Blad: “Some of my mates thought I had been a bit too active on the ladies front recently and wanted to punish me.
“When we were in the restaurant on Monday, they said I had to tattoo a Barbie doll on my bum, or the receipt on my arm.”
Which is obviously a very good reason to get a tattoo, as we all know. You couldn't possibly say "hell no!" in a situation like that.
Unsurprisingly his parents weren't impressed. At all.
Speaking with the Expressen, Stian explained: "I got an email from my dad that wasn’t entirely positive, saying “What on earth have you done?! Do you think you are coming home with that!? Your mother has had a break down.”
The artist at Sabelink Tattoo, where Stian got inked, posted a photo of his work on Facebook, captioning it ‘my strangest tattoo so far’.
The image has been shared 230 times and has more than 1,000 likes - and perhaps it is for this reason that Stian has said he has absolutely no regrets.
"It’s funny to think that I have a tattoo which no one else even has the likes of. Even the date and time is on it."
We suppose that's one way of looking at it...
