At Interlochen in Michigan. There was always a statue of a bear on campus, and it was a tradition for everyone just to pee on the bear. Usually just done at the end of the year cause it’s usually snowy during the rest of the year. Started by academy kids, no idea how it really started. I actually did it once. It was funny because sometimes people who didn’t know would sit on the bear, and it was really gross.
There is a really weird tradition, but it makes sense that it would come from a bunch of kids at an away-from-home school.
