Political pollster's term for defecation constant wherein a percentage of data used in projecting election results based on exit polls is assumed to be shit because voters say one thing to be seen as having voted for the winner but actually voted for their enlightened self-interest.
Fucking Defcon is 87.6%, Mondale is fucked.

With influences from Megadeth, Delian League, Dream Theater, Metallica, Pantera, Iron Maiden, Metal Church, Iced Earth, Mudvayne and Slipknot. with their own unique metal sound these guys rock hard, hence the fact that "DEFCON are better than your favourite band!" - Keep A'rockin you guys.

A defense readiness condition (DEFCON) is an alert posture used by the United States armed forces. The DEFCON system was developed by the Joint Chiefs of Staff and unified and specified combatant commands. It prescribes five graduated levels of readiness (or statuses of alert) for the U.S. military, and increase in severity from DEFCON 5 (least severe) to DEFCON 1 (most severe) to match varying military situations.
DEFCONS are a subsystem of a series of Alert Conditions, or LERTCONs, that also includes Emergency Conditions (EMERGCONs).3 DEFCONs should not be confused with similar systems used by the U.S. military, such as Force Protection Conditions (FPCONS) and Watch Conditions (WATCHCONS), or the Homeland Security Advisory System used by the United States Department of Homeland Security. The highest confirmed DEFCON ever was Level 2 (DEFCON2). Movies and popular culture often misuse the DEFCON system by "going to DEFCON 5" during a state of emergency. In fact, DEFCON 5 is the lowest state of readiness. DEFCON 1 is the most severe.

Defcon 1 is a code used amongst guys for when a woman is at that time o the month and should not be argued with, agreed with or even spoken to. God save any man who's girlfriend is at Defcon 1.

Defcon 2 is achieved when there are either 2 Women at Defcon 1 or if one Woman is so far into Defcon 1 she is psychotically raging around destroying all in her path. May God have mercy on her boyfriend's soul.
Guy 1: Hey man, whats up with your girl.
Guy 2: Defcon 1 man.
Guy 1: *makes sign of the cross* Godspeed.
