There was this dude in Philly back in the mid 90's named Wild Bill who used to do kickflips down the city hall 6, and crooked grinds and shit on the Love ledges on a longboard.
Granted it was the type of longboard that looked like a stretched out version of a regular board and not these sector-9 type shits, but it was still a longboard.
I think he even came off in a 411 doing said kickflip down the city hall 6.
Dude was the homie, but he was a little off his rocker if you know what I mean.
Hence the name.
