This is my favorite from urban dictionary:
A skier or snowboarder who sucks and is usually
spotted wearing clothing from 1983, but other clothing styles for them
do exist. A dead giveaway of a gaper is when their pants are tucked
into their boots and the famous "Gaper Gap" (a gap between the
helmet/hat and the goggles). Gapers sometimes temporarily inhabit the
entrance to a terrain park. They will sit on their ass for a good 5-10
minutes talking about what they are going to do of a that "jump" or
"rail" while everyone behind them goes before them and they stare at
them with their mouth gaped open. Once they finally decide to leave
their home at the entrance of the terrain park, the gaper will
eventually decide to either roll over the jump and mess up all the
lips, or they will try and actually hit the jump. If this occurs, they
generally end up coming up half way short of the landing on their ass
and
yardsale,
while the person behind them runs them over and/or yells at them.
Gapers may also make turns or snowplow down green runs and sometime try
to act cool by crouching and sticking their ski poles in the air but
are totally oblivioius to the fact that they look even more stupid than
they previously were. Gapers often find themselves on the top of a
black diamond run because they are dumbasses and can't read a map. When
they approach the run, they may either turn around, stare at it, sit
down on the top of it, or just simply walk down the side of it. Gapers
often have trouble getting on and off lifts and the lift operator gets
really frustrated with them because he is required to stop the lift. A
fun game to play while skiing or riding behind a gaper is called
"Follow the Gaper". The game is played by following the gaper's path
and looking as bad as they are. The game will usually last until they
identify your presence, however it is possible to extend the game even
past this point.
That gaper just stopped the lift when he got on and off of it!
That gaper's Salomon Symbio rear-entry ski boots are so sick!
