PAX
The best gaming convention/festival in the world.

In 2004 Gabe and Tycho of Penny-Arcade.com wanted to attend a con that had equal parts tabletop gaming, computer gaming, and video gaming--and that wasn't just a big marketing event for some lame corporation. They didn't find any, so they decided to make their own.

Thus was the Penny Arcade Expo (PAX) born. The first show drew over 4,000 gamers from all over the world to bear witness to 48 hours of nonstop gaming, four nerdcore concerts by the likes of Optimus Rhyme and MC Frontalot, the world public playable premier of Halo 2, and the 2-day multigenre $25,000 Omegathon tournament (which culminated in a final match of: Pong).
"Essentially, Tycho and I wanted to throw a big-ass two day party for gamers, and everyone’s invited."--Gabe

“I did have to take 3 days off work and spend more money then I usually do, so I have like, 6 bucks in my checking account at the moment… and my next paycheck will be small and mostly go to car insurance... But goddamn it was worth it.”--Forum post

"Did anyone else notice that everyone you passed at PAX looked vaguely familiar? Like we all have a sort
of “geek” look to us and therefore recognize our own kind? It was strange and comforting at the same
time.”--Forum post

What posh English kids (especially at boarding schools) say to each other when they want to stop fighting.
The Latin equivalent to present term mercy.
Often referenced in "The Famous Five" by Enid Blyton.
Julian: "What say you Dick we have a little tussle to see who get's the last cucumber sandwich?"
Dick: "Come on then old chap!"
(They tussle)
Dick: "Pax! Oh I say you win Julian"
Julian: "Oh terrific. I'll race you back to Aunt Fanny's!"
