On our school's field trip to go skiing, some kid brought a 5 dollar plastic snowboard from target...
Another gaper snowboarder said "Yeah, I hang out on the easy runs because I like to watch noobs fall." When I asked him why he wouldn't try any black diamonds.
I also know another gaper snowboarder who claimed "Yeah, last year I accidentally did a backflip 180, I forgot how to do it over the summer though." I pretended to be impressed, and asked what the coolest trick he could do now was, he said a 360 tailgrab. I said, "Cool, show me." He hooked an edge going up the jump and faceplanted. I later heard him telling his friend "I would've landed it too, its just that some idiot made a rut in the jump."
And I once saw a snowboarder with poles, he looked around 18-ish, and he held the poles upwards behind his back making an X.
Wow, what a text wall, last one: Saw a snowboarder fall off the lift, only like 10 feet or so, but I was like 2 lifts behind him, and they stopped the lift for like 15 minutes. I hated that kid.
