So, non scandi SKAM fans that will probably try to watch the 2 previous seasons during the hiatus:
Some of you are possibly going to be a bit confused about the whole russ concept.
The first ep starts with Vilde having the whole toilet paper situation, talking about her conflict with the other girls on her buss, and the second season have the penetrators/riot club and yakuza boys. This is all related to the kinda confusing Norwegian russ graduation ritual.
Norwegian high school graduates are called russ. For the month of May until 17th of May (Norway’s national day) the russ wear red or blue pants according to what subjects they have specialized in at school, blue means economics, red is general education. Russ usually also have some form of party vehicle that you buy and style with your squad, it started out as cars but today kids that can afford it buys a whole buss. This is more usual in some schools / areas than other, Oslo and the west side of Oslo is sort of the main centre, in most of the typical buss schools there will be several busses. They decorate this according to the buss crew/squads chosen theme. The russ that care about this will save up and prepare for this for the three years they attend high school. One of the normal things to do is buying toilet paper or cookies in bulk and sell for profit, getting sponsors, and also of course have a job on the side. Some russ still choose to use a car or a bike or walk but for some, this is a huge deal. The busses usually have a cover theme and a final theme, they have crew jackets, hoodies, stickers and even songs written and produces that fit this theme. So in SKAM the penetrators are the cover theme and the riot club is the final theme. The busses drive around as rolling clubs during May which is called rulling (rolling).
A very fun part of being russ is that all russ have special rules and challenges that you can choose to complete and everyone knows this so when you wear the blue or red pants that means that people won’t react weirdly to you doing crazy stuff since everyone knows this is part of the dare thing. One challenge can be to swim in the ocean before May, to buy a condom at the store only using mime, crawl from the parliament to the royal palace, drink a certain amount of beer in a set time and so on. The russ also have russ cards that are sort of mock business cards with jokes on them. Young kids LOVE these and collects them.
So that’s the explanation of a weird and pretty unknown part of Norwegian culture, russ is basically mini temporary frats / sororities (they can be mixed gender, but normally you have girls busses and guy busses)
