OMG this is awful x_x . i hope the other guy is ok and recovering
but anyway , although this was unbelievably stupid , i have seen guys do a lot of stupid things like (true story) slapping each other so hard until one of them loses by saying "ouch" . girls too do some pretty stupid things in competition with other girls (although a lot less dangerous ) . it doesn't necessarily involve other people's admiration , it's just in human nature , the animal desire to feel superior to peers
