I'd like to dedicate this node to one of the greatest, especially where originality is concerned, lexicographers of all times. Douglas Adams, along with John Lloyd, compiled "The Meaning of Liff" followed by the completely revised, modernised and generally plumped up "The deeper meaning of Liff.
The books combine the hundreds of situations, emotions and objects for which no words exist with an equal number of potentially useful words that waste their time lurking on signposts around the world. The result goes along the lines of:

    Corriemuchloch (n) : The kind of person who can make a complete mess of a simple job like walking down a corridor.
    Simprim (n) : The little movement of false modesty by which a woman with a cavernous visible cleavage pulls her skirt down over her knees.
