Hey Riikka. You claim once more that your English sucks, and I'm gonna thump you with about 2kg of Swedish/English dictionary when I see you next. Your English is better than mine. Moshing is the um, not-dancing traditionally performed to punk and grunge. It invloves a lot of leaping around, flailing your arms, injuring yourself and others, and generally being violent to the space around you and everyone in it. It's great, even if I seem to be too old for it these days. As far as I'm concerned, the choruse of Smells Like Teen Spirit is quintessential moshing music.
