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 merely to be breathed in public, the perpetrator would be shunned, barred from polite society, and in extreme cases shot through the lungs, are now thought to be very healthy and proper, and their use in everyday speech and writing is seen as evidence of a well-adjusted, relaxed and totally un****ed-up personality. . . . But even though words like “joojooflop,” “swut,” and “turlingdrome” are now perfectly acceptable in common usage there is 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 for use in Serious screenplays.
There is also, or was, one planet where they didn’t know what it meant, the stupid turlingdromes.
