commonly mispelled as skieer, skiir, skiieer, or idiot, a skier is someone who has no fear. A true skier (there are many imposters) can "ride" a whole mountain. THey are able to pull insane tricks, like double-backflip-900-helicopter-indy grab to switch-triple-frontflip-360- nose grab. They can also ski in light snow called "powder" while defying the laws of gravity by not sinking in. A true skier is a great athlete, and can generally do loops around a snowboarder in any part of a mountain.
a. True Skier - Bode Miller, Glen Plake (see Mohawk)
b. Wannabe/Poser/Lame Skier - One who "pizzas" and generally either gets in your way, slows you down, or runs into you.
WARNING - avoid type b at all costs and if possible, run into them
