The point where one cannot hold her their bowel movement, typically diarhea. The body stiffens up like a wooden board, hence the name 'boarding'.

Quick movements while boarding may cause one to shit their pants. Famously discussed by former Dodger's pitcher George Brett regarding an incident of food poisoning in the Las Vegas strip.
Mike and Dave both started boarding shortly after over-eating at McDonalds.

(verb) while snowboarding, getting stuck on a particularly flat part of a run because you don't have enough speed or wipe out, thus eliminating any forwards motion. Because snowboarding requires some sort of downwards slope to keep moving, you will most probably be forced to un-bind. It is very annoying, and happens commonly to beginner snowboarders that are not yet practiced enough to take steeper runs, and so are forced to take runs that are meant to be 'easy', but in their flatness are really only easy for skiers.
Dude, don't take that run I just did. It's so flat, all you'll do is no-board.

Awh, shit. That was a epic fail. I'm stuck no-boarding. I have to either un-bind or jump until it slopes again...
