In today's modern Galaxy there is of course very little still held to be unspeakable. Many words and expressions which only a matter of decades ago were considered so distastefully explicit that were they to be merely breathed in public, the perpetrator would be shunned, barred from polite society, and in extreme case shot through the lungs, are now thought to be very healthy and proper, and their use in everyday speech is seen as evidence of a well adjusted relaxed and totally un(bleep)ed up personality.

So for instance, when in a recent national speech the Financial Minister of the Royal World Estate of Quarlvista actually dared to say that due to one thing and another and the fact that no one had made any food for a while and the King seemed to have died and that most of the population had been on holiday now for over three years, the economy wa snow in what he called "one whole joojooflop situation", everyone was so pleased he felt able to come out and say it they quite failed to notice that their five thousand year old civilization has just collapsed overnight.

But even words like joojooflop, swut and turlingdrome are now perfectly acceptable in common usage there is still one word that is still beyond the pale. The concept it embodies is so revolting that the publication or broadcast of the word is utterly forbidden in all parts of the galaxy except one where they don't know what it means. That word is 'belgium' and is only ever used by Zaphod Beeblebrox in situations of dire provocation.
