Sep 17 Word of the Day
Fredagsmys is pretty much the most holy tradition of Sweden. The word origins from two words; β€œfredag” and β€œmys”, which roughly translates to Friday and cozy. Every Friday, all Swedes drive by the supermarket to buy ingredients for taco, soda and chips. Then, they all sit down in their sofas with their families or friends and watch telly. Usually, the parents fall asleep after a few glasses of wine or beer while the kids stuff themselves with chips until they have a stomach ache.
Now it's the end of the week; it is time for fredagsmys!
