LDP stands for Long Distance (Skateboard) Pumping, also known as "Skumping." Longboard-skateboard technology has rapidly advanced since the 1970's, and along with those changes is a new breed of distance-pumping skateboarder.

LDP 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.
We usually go for a few LDP sessions each week, come check it out!

Lie Down Piss

The absolute laziest piss a man can take. To be used when describing serious slacking.
"Are you taking an LDP or what?"

"This is no time to be taking a LDP man"

"What are you up to?" "Not much man, just taking an LDP really"

Used to describe a friendly wager between two parties in which it is understood that the loser doesn't pay (ldp) the value of the bet. It is simply a fun bet with a monetary value, where no money exchanges hands.
Ok. Let's put some money on this. I'll bet you $100 that Cleveland beats Washington, ldp.
