I agree with SAP dude, it is disturbing but not surprising. Doing these things in group and recording the acts to bring to public is quite...... 'ke bhanne ' i dont have words. Again, i am not saying these kids are doing good things, but these kinds of activities were there even 25 years back as SAP dude says. It is true that the magnitude of such activities have increased in recent years probably because of western cultural effect and peer pressure.  I have seen/heard many such incidents while in hostel in kathmandu around ~25 years back. Even in villages, there used to be boys' 'gaff' how they made it with their classmates after SLC exams etc. There even used to be narratives by senior dais (boys in 9/10 class) ~ 25 years back of the incidents with girls who went  to participate in 'birendra shield' along with them. I believe that used be with girls whose Dad or Brother would not accompany them to the game venue. Again, i am not saying this would happen to all the girls whose gurdains would not accompany them nor i am generalizing. Just saying, how forward were girls/boys even in villages in those times. I was not sure, if i should have brought up this issue here, as these are something people do not like to talk as those events are not considered moral.
