DEFCON is an annual computer security conference held in Las Vegas.
A DEFCON FAQ on an apparently non-affiliated website uses sexist language like the following to describe computer security activities:
Q) Can I get Internet at Defcon? Is there wireless access at Defcon? Who should I not connect to, and what should I be connecting to?
A) Use the internet at DefCon at your own risk. You will be sniffed. You have been warned. You may end up on the Wall of Sheep. Using wireless at Defcon is kinda like your computer saying to everyone else at the con: "I bet you can't fuck me.." "OH YES I CAN!" "No you can't!"... RAPE.
