So, I guess that this has been a thing in different pasts of Sweden (this is from Lappis) for a while (possibly since the 70s). From the background I’ve found, this happens nightly at 10:00 pm, and is a way for the students of the area to release their inner wolves (and frustrations). I’ve got to say that I’m kind of liking this tradition. Just think how awesome it must feel afterwards, with all of that stress released.
Check out the Flogsta screams (like this one) as this seems to be the original start of the tradition. This seems like an appropriate start to the week, doesn’t it? ; )
– found through…yup, Reddit (wish I’d heard about this one much sooner)
