PDN = Proctologically Derived Number. An obscure mathematical classification for almost all numbers, including dollar amounts, presented to the public by governmental entities, politicians, pork-barrel government contractors, and other self-righteous prevaricators, with the sincere claim that the number is totally based on sound science, fiscal integrity, and the public's best interest. PDNs are typically presented as having at least an order of magnitude higher accuracy and reliability than the more commonly used WAG (Wild Ass Guess) classification of numbers. A sub-classification of PDNs is the LBSPDN (Loose Bowel Syndrome PDN), typified by numbers presented in such a manner or quantity as to inundate the public, leaving them flush with bewilderment.
The proposed Federal budget presented by the Bush Administration to the Congress, and the American people, is a fathomless melange of obfuscated PDNs.

Get the PDEA mug.Personal Defense Weapon. Originally used to describe HK's MP5K (MP for Maschine Pistole or Machine Pistol and K for "Kurtz" meaning small). The term has since left being used to describe that weapon and has grown to represent a new class of weaponry that is supposed to have the firepower of a rifle (such as a M16 series rifle in 5.56mm)yet the ease of carry of a submachine gun (like the larger MP5 variants).
Two weapons currently fit such a description, FN Herstal's FNP90 (5.7x28mm)and HK's MP7 (4.6x30mm). Both of these weapons are marketed as being perfect for support staff and pilots where a full size rifle would be too large to be practical
