Thoughts on crowdsurfing

I read punk/hardcore fans started doing it then it caught on to heavy metal fans when they started coming to some thrash shows.

I kill crowdsurfers. I carry an extremely sharp but very small penknife with me to any gigs I go to. If someone crowdsurfs on top of me, I take it out in a matter of seconds and get it inbetween a couple of their vertibrae. No more idiot crowdsurfer.

If that isn't a confession, I dunno what is.
