Parkour

Parkour (sometimes also abbreviated to PK) or l'art du déplacement[1] (English: the art of movement) is an activity with the aim of moving from one point to another as efficiently and quickly as possible, using principally the abilities of the human body.[2] It is meant to help one overcome obstacles, which can be anything in the surrounding environment—from branches and rocks to rails and concrete walls—and can be practiced in both rural and urban areas. Parkour practitioners are referred to as traceurs, or traceuses for females.[3]

Parkour, in truth, is the cultural equivalent of a Dan Brown book. A lame idea wrapped up in a lot of window dressing, it's just jumping off stuff, as the above hero proved. But then this is coming from someone who'd walk the long round to avoid letting people see that he gets short of breath scaling a low dry-stone wall.
