“The Flogsta Scream” takes place every night at 10pm in the Swedish university town of Uppsala, specifically in its Flogsta neighbourhood. As you can hear in the video, some of the people really unclench their butt-cheeks and let loose. The wiki: “There is controversy over how the tradition started. Some locals say it was simply a stress reliever, which started during exam times and then became a daily occurrence. Others say it started in remembrance of a student who committed suicide in the 1970s.” I prefer the former explanation. We have the heritage horns sounding noon from Canada Place and the 9pm gun in Stanley Park, but a city-wide, nightly scream session (to vent against the high cost of living, NIMBYism, Ed Hardy, The Province newspaper, and Earls) would make a huge difference in our general happiness index.
