PDN stands for "Public Displays of Narcissism".

1. When 2 people display and inordinate combined fascination with themselves.

2. A spectacle of excessive connected self-love between 2 people; vanity squared.

3. When 2 people excessively and publicly compliment themselves as if they are one person.
Scenario: Guy and Girl comment on a photograph of themselves.

Guy: We've got the look......whatever that look is.... well we've got it.....emo?

Girl: We are the king of emotions.

Guy: King status....nice. It's good to be the Kings.

Girl: Nope. King. With our power combined we are a king.

Guy: Our narcissism is getting pretty high but then a healthy dose of confidence is usually pretty sexy.

Girl: And our combined narcissism is almost too much to bear!

Guy: Oh what are we to do with us?

Girl 2: I love how all the comments are by you guys, for you guys, about you guys! Total harmony!

Guy 2: Agreed, too much PDN, get a room!

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.
