The act of doing (or in reference to) cocaine. Derived from the fact that the powdered cocaine can coat a razor used to divide up lines, causing the blade to be covered in "snow"
"Dude, was she snowblading earlier? She's drawing crazy shit all over the coffee table"
"You wanna snowblade?"
Usually, about 1 meter long slivers of material strapped to the feet for use in downhill propulsion in snowy areas. Commonly referred to as "fruit boots," these blades or "trick skis" often belong to rediculously extreme skiiers-gone-wacko enthusiasts of winter sporting. Not for the faint of heart, blades become the badass little brothers to traditional downhill alpine skis.
"Damn, did you see the snowblades on that animal?"
Snowblades are small twin tipped ski's. To use requires no skill, style or consideration of other slope users.
A bit like rollerblading on snow with the same annoying characters doing the "sport".
The most fun to be had is to cut the little f@#kers up and watch them face plant whilst going past on your propper sized snowboard or skis.
Look at that snowblader falling on his arse... oh he got up, and he fell over again, and he got up again, and he fell over again, etc etc etc etc.
