defcon 1 

We're all dead.

Defcon 1 was activated when the confederacy of jackasses and penises took over China and got ahold of their nukes, and proceeded to nuke the planet.

defcon 5 

adj.
n.
A state of crap defecation that is so foul in smell, the defecator must make every attempt possible to relieve himself of the odor.

These attempts may be:
Opening the window.
Turning on a vent.
Spraying Lysol (or other powerful positive odors) around the room.
Covering of the nose.
Opening the door.
Repeated flushing.

And a last resort: Leave the room immeadiatley, hoping the smell will dissipate.

A grumper often results in defcon 5.

Roommate of Defecator: Hey what's that smell?
Defecator: My grumper hit Defcon 5.
Roommate: DEFCON 5!?

defcon scavenger hunt

The Defcon Scavenger Hunt is a ridiculously-themed, fast-paced hunt across the city of Las Vegas by a bunch of hackers to prove how people can obtain a million strange things in a single weekend.

This year I participated in the Defcon Scavenger Hunt and talked to tons of new people and almost ended up in prison!
