Someone who fakes talent at Surfing, Skateboarding, and Longboarding. They will most likely show up with a brand fucking new setup that's top of the line, and that setup will most likely be incompatible with there style of riding (e.g. 85a slide wheels on a downhill board). The kook will also most likely use incorrect terminology, sounding like an imbecile. Avoid kooks at all costs.
Kook: "I just did the steeziest toedge skid today on my downhill. I was going like 100mph on my local hill, with my Evo set with 65mm 85a wheels and non-spaced bearings! I also did some freeride, but there was too much thane on my bearings."
Normal Longboarder: "Today was pretty good, I had to sweep some shit out of the road, but the run has great corners to predrift or rail. My Arbalest with 78a 76mm wheels was doing great, the new wheels thane really nice. I was going to do some freeride but I forgot my slide wheels."
