The Meaning of Liff

The Meaning of Liff is a humorous dictionary written by Douglas Adams and John Lloyd.

It is "[a] dictionary of things that there aren't any words for yet". All the words listed are place names, and describe common feelings and objects for which there is no current word. A typical example is:

Shoeburyness (abs.n.)

The vague uncomfortable feeling you get when sitting on a seat which is still warm from somebody else's bottom

The according to Adams' account in The Salmon of Doubt, the Meaning of Liff grew out of an old school game, and started when he and Lloyd were on holiday together.
