I found it! In a thread I cannot now locate (yes, I tried the Forum search for what I thought it was about), I mentioned that I had a Gaelic something that is along the lines of Ladle Rat Rotten Hut, or (more closely) Mots d'Heures Gousses Rames. Anyway, I found it today: it is from Myles na gCopaleen, aka Flann O'Brien, according to the handwritten note on it. It goes on for pages and PAGES. I cannot read Gaelic any more (when I was in Ireland it kind of came to me) so I can't appreciate it myself. And it's WAY too long to copy. Anyone interested can send me a fax number, though, it is really very interesting.
Looking through it now, I see that it also has some paras in English, one of which is a little dissertation on how Irish peasants (I'm quoting here) have a vocabulary of 40,000 words or so, whereas the Eglish get by with a mere 4000...One claim is that "it is a nice speculation to what extremity one would be reduced if one were locked up for a day with an Irish-speaking bore and bereft of all means of committing murder or suicide... There is scarcely a single word in the Irish (barring, possibly, Sasanach) that is simple and explicit...Cur [can mean] ... a heron's boil, a leprechaun's denture...the scum on the eye of a senile ram... a goat's stomach-pump ... "

It's a howl.
