Also, ska fans are some of the most shameless people on earth when it comes to skanking. My friend dragged me to a Battle of the Bands where I sat through 6 hours of fucking wretched screamo bands from New Jersey just so we could support his cousin's ska band. Mixed in with the wretched screamo bands were mostly wretched ska punk bands, and one of these asked their fans to form what they called a "penguin pit" in which you waddle like a penguin instead of skanking or moshing and "make as big an ass out of yourself as possible."
Interesting (if headache-inducing) experience.
