look up any word, like jamflex:
 
1.
A religious national holiday set forth for the day of November 9th.

It is a day where everyone takes a day off to throw a gigantic, medium-sized, and/or small LAN party for what-ever game they desire.

This day can be used for the sad excuse of staying home for the release of Halo 2, and/or playing it with a house-hold of friends in a LAN-party ordeal.

The origin of the term is from a comic of Ctrl + Alt + Del.
"I'm sorry Ethan, I'm going to need you here in the store. I can't let you take time off just so you can play Halo 2 all week!"

"I need the time off for obervance. It's a religious holiday."

"Oh yeah? What Religion? What Holiday?"
