The Law of Double Penetration: It's only gay if your balls touch.

Briefly, "the realization that each random passerby is living a life as vivid and complex as your own." Originally from the Dictionary of Obscure Sorrows, which has a lot more beautiful neologism definitions like this you might enjoy.

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!
