I am reminded of a supposed dictionary of sexual things called The Gentleman's Guide to something or other(perhaps the alphabet?), where the definitions were little poems or limericks. I wish I could remember some of them, I do recall that O was Onanism (which I had been pronouncing one-anism and thought that the crime was that there was only one of you there till I read this book...) - I am also reminded of Edward Gorey's limericks like They had come from the fugue to the stretto / When a bearded young man from the ghetto / Reached forwards and grabbed / Her tresses and stabbed / Her to death with a rusty stiletto.
