@spendius,
So the challenge of getting words with the letters X, Y, Z or ending in your terrifying space of LY is foreboden; but you think creating 'witty' sentences is a proper challenge. Who the hell are you to decide? If you want to do that, then I believe hyphenated crap like Lickham-Bottom shouldn't be allowed, it's a miserable excuse to create excessively long 'words'. I resisted such an urge earlier when I toyed with the idea of ultra-unusual, felt it more important to use non-hyphenated words/places.
I seem to recall years back, you used to balk at long words, made a stink over that as well.
As I said yesterday (am I allowed to use that word as it has 2 ys in it?), although there aren't many words which begin with the aforementioned letters, there are littering the thesauruses, dictionaries, vocabularies literally millions of words with those letters. If the placement words and the chosen Acronym word are to exclude these letters then there really isn't much hope for this thread. No longer can sizzle, mixture, exotic, cyborg, amazonian, hieroglyphic, eyewash, taxpayer, be allowed as well as a whole host of other words.
Too, isn't it more the challenge to take those few words starting with X, Y or Z and find ways to intersperse them into formed phrases (witty or just plain regular and holding clarity)?
