Actually, it is not Seattle. It's Chapman University in Southern California, where Jacob Authier, a student in his third year, has been walking around shirtless. The story by David Epstein has been published by Inside HigherEd.
Interestingly, the only ones who even notice this are some of his fellow students who have formed some kind of a fan club!
[...]He’ll often paint his nipples black, or, on special occasions, some more festive color, like green for St. Patrick’s Day. He said he’s considering candy cane swirl nipples for Christmas this year. For Valentine’s Day, Authier’s brother Joe, a sophomore at Chapman, used a pocket knife to carve a heart – not the cartoon kind, but one with veins and ventricles – into Authier’s chest, and wings on his back. Authier said the wing markings have faded, but the heart “was cut a little too deep,” and the scars are still there.
There is other such weird stuff in the story. The really amazing thing is that the faculty don't really seem to mind.
