The authors' rationale was that there are loads of everyday things, recognisable sensations and familiar situations for which the English language lacks a precise name. At the same time there are tonnes of interesting words, which look like reasonable names for these things, doing no more than sitting around on road signs all day.
So they decided to pair them up.
Hence if you ever find yourself, for instance, abruptly discovering you've been hearing a song lyric wrong all these years: well that moment of discovery, according to this book, has a name: a rhymney* . Or you know when someone in a crowded room is attempting to tell another person something private, rude or plain weird, just as everyone else falls silent? Well, now you can measure the precise loudness and/or embarrassment of this statement as a lulworth* . A droitwich* is the little hopping dance performed by two pedestrians each attempting to give way to the other and failing. And so on.
In Real Life the real Liff is a Scottish village, in Angus near Dundee. Its 'meaning', as given in the current edition of the book, is appropriately:
- Liff n. A common object or experience for which no word yet exists.
The idea was sparked in a conversation Adams and Lloyd had while on holiday in Corfu in 1978 (when the former, a Ridiculous Procrastinator, was 'attempting' to write The Hitchhiker's Guide to the Galaxy), based on memories of a school assignment the young Douglas was once given — which may itself have been based on a 1950s essay by English humorist Paul Jennings: Ware, Wye, Watford. Some of Liff's 'definitions' originally appeared in the Not the Nine O'Clock News calender, and "glossop" and "scrogs" are mentioned in the additional material in the Blackadder: The Whole Damn Dynasty script book; both shows were directed by Lloyd.
A revised and expanded version was published in 1990 as The Deeper Meaning Of Liff, though a further revision (after Adams Died During Production) for 2013's 30th anniversary restored the original title. In 2012 a sequel, Afterliff, was published, compiled by Lloyd and Jon Cantor with added liffs submitted from fans and famous friends.
- Zeerust n. The particular kind of datedness which afflicts things that were originally designed to look futuristic.

- Bread, Eggs, Milk, Squick: The definition for "nacton" gives the examples fish 'n' chips, mix 'n' match and assault 'n' battery.
- The definition of "toronto":Generic term for anything which comes out in a gush despite all your careful efforts to let it out gently, e.g. flour into a white sauce, tomato ketchup on to fried fish, sperm into a human being, etc.
- "Belper":A knob of someone else's chewing gum you unexpectedly find your hand resting on under a desk's top, under your car's passenger seat, or on somebody's thigh under their skirt.

- Self-Deprecation: The book originally bore the tagline "This book will change your life", either as part of its cover or as an adhesive label.
