skigasm 

That moment when you wake up, usually hanging from a night on the lash, to sunshine and a foot of fresh pow, causing you to violently jizz in your pants.

This can also occur when watching skiporn, before you shred a line, whilst shredding a line or when you see an absolutely bangtastic female skier.

Skier #1: Mate, look out the window, it's fucking fantastic
Skier #2: Oh my fucking god...I'm pretty sure I just had a skigasm
Skier #1: Let's go shred that shit

shigasmeze 

The rare act of shitting, orgasming, and sneezing all at the same time. The ultimate pleasure. Typically so intense that the party committing the act spontaneously combusts.

We all miss Smitty. A man of rare gifts. One to attempt to experience all of the world's pleasures; until the day he happened to glance at the sun while receiving oral sex on the toilet. The burst of flame was witnessed for miles and his cries of pleasure shall be remembered for generations to come. A Shigasmeze for the ages.
