Today SVT reports on live broadcasts on social media. Similar news came earlier this year when police in the Stockholm area warned that guys "urge" each other to fight in front of the public.
In order to understand young men's live battles, we must take into account the near-symbiotic relationship between masculinity and violence. Men can be said to be experts in violence.
Of course, not all men fight, but the ability to give and receive blows has long been central to notions of masculinity. However, there is a difference between violence against women and violence against other men.
In the book Of the More Sensitive Kind, I show that men see female violence as something deeply shameful, while violence against men is not at all morally problematic. As one of the men interviewed puts it: "It's almost better to be a known killer than to beat women."
This is confirmed by sociologist Sara Uhnoo's research on young people's views on violence. Of course, it is wrong, they say, but at the same time completely in place that guys fight with each other.
By fighting each other, guys can appear as strong and "real" men. Violence gives high status - even if you lose and get hurt.
Few have portrayed men's relationship to violence as sharply as Chuck Palahniuk in the novel Fight club and filmed by David Fincher.
It describes the emergence of a secret society where men meet to fight. The Fight Club is a male community in a meaningless and over-commercialized world.
The violence also makes soft men tough and confident , in the film embodied by the well-sculpted Tyler Durden (played by Brad Pitt). His opposite is testicular cancer patient Robert "Big Bob" Paulson (played by soft-rocker Meatloaf), who has completely lost his mandate. The former bodybuilder is a thick lip sill that, as a result of hormone therapy, has developed breast and light voice.
If the cardinal rule of the fight club is never to tell them about it, today there is a plethora of public accounts and pages on social media completely dedicated to violent material.
They often show settled fights between two people, but just as common are videos with assaults of individual or spontaneous fights in connection with nightlife. The pages emphasize the recurring importance of showing a tough manhood, says criminologist Mark Wood.
Medial self-representations of violence and crime may not be as new as it seems. Many professional criminals have written autobiographies, such as Lasse-Maja, whose book made the criminal a national celebrity as early as the early 1800s.
The new thing is that we now have social media. From being a few creators and the mass consumer, cheap mobile cameras and digital platforms have made film something we all have the opportunity to produce and distribute.
But live battles cannot just be seen as a direct result of technological advances. It also relates to our tendency to show off and create ourselves before others.
Today, many of us are dedicated to showcasing our lives and ourselves online - our travels, parties, homes, friends and families. It's like we need to be seen to confirm not only our social status, but perhaps our very existence as well.
It may seem contradictory to film your own and friends' crimes, as it risks being used as evidence.
But digital technology and our constant presence on social media means that ongoing violent crimes are no longer just documented, but the desire to be seen can now be a driving factor behind young people's criminal acts.
