Skump is short for "skateboard pump", since skateboard pumping and longboard-skateboard technology has rapidly advanced since the 1970's - along with those changes is a new breed of distance-pumping skateboarder. Skump sessions can be casual 5- to 10- mile pump cruises on flat bike / rollerblading trails, or a 26-mile all-out marathon, where a gyrating, pumping motion is the primary means for moving the skateboard forward! Check out skumping.com for articles, videos, and current information on this growing niche of skateboard pumping.
