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.

To skump endlessly, is to reach nirvana. -Mahatma Gandhi
