Today’s word, flollop, is used in Douglas Adam’s book, Life, the Universe, and Everything, to describe the movement of a mattress:

The mattress flolloped around. This is a thing that only live mattresses in swamps are able to do, which is why the word is not in more common usage.

In the book it is argued that in an infinite universe everything must grow somewhere, including mattresses. Well sponges grow on our world, so why not mattresses somewhere else!

Mattresses also globber when “deeply moved by a story of personal tragedy”, vollue, willom, flurble, gup and flodge, though the latter actions are not clearly defined.

If you have read the story in language other than English, do you know how these words are translated?
