Replying to NEED SKI TERM DEFINITIONS. possible reward of fame and women

So I'm writing an article about skiing, being a park skier myself. Next to the article will be a nifty column of ski terms that people normally wouldn't know. Rather than fucking up the definitions by making them up on my own I decided to ask you people.

So please give your own definitions to the following terms or feel free to add more.

Hippie Killer: Slide one ski on top of the box and then kick the side with the other ski so you spin around. “Andy Perry is bomb at hippie killers”

Nose Butter:

Rainbow Rail:

Futurespins:

Afterbang:

Pillows:
