SilverFish 

The worst longboarding internet forum in existence. What was once a place to go and learn about an upcoming sport has turned into a dive; where teenage douche bags convene to bitch and moan about how monumentally expensive a new set of wheels are.

Average SilverFish member (Teenage Douche) - "I was about to use my moms credit card to order some FlyWheels but Abec 11 increased the price by four dollars. I'm not even joking, the manufacturers screw me over every chance they get."

Endangered SilverFish Minority (Logical Young Professional) - "Shut the fuck up you ungrateful bitch. No one is asking you to longboard. In my day I earned half as much, yet I still managed to afford an ounce of headies every month."
