skumping 

The act of skateboarding long distances over flats and inclines without touching foot to ground, using perpetual surf-like pumping motions, sometimes switching between "goofy" and "standard" pump stances. Longboards for Skumping are generally in the 36" - 43" length range with 25"+ wheelbases, longer than skateboards used in Giant Slalom racing.

"That dude's skumping uphill!"

"We just finished a 10 mile skump session!"

The act of taking a dump while on Skype.

Admit it, you have found yourself on the phone while on the crapper. Skumping is the evolution of this act.
