2.
skateboard slang - when the skateboard hits you in the shin... usually not a big deal but hurts like you-know-what for a few minutes. imagine if someone just walked up to you and whacked your shin with the edge of a skateboard... it ain't fun, and it leaves a big purple mark on your leg. after 4 or so years of skating your legs should look like cobblestones, but its all good cause now you are a good skater.
i was just trying a 360-flip and got a mad shinner... it got better pretty quick though.
