I do parkour, i am wondering who knows what. Whenever i ask someone about it they be like wait hardcore what, what that. Then i be like no dipshit parkour and soo on so who no wut it is

It's the fastest way around an obstacle corse or obstacle there's such a thing as free running but that focuses on tricks not speed and if you do it how do you not know what it is?

when you can jump, climb, and dive around things without a sweat. Its kinda like a ninja

I know about it, so do my parents, and all my friends and most the kids at my school.

basically obstacle training, like jumping, diving etc...
