Yes, yes, I know: Pratchett doesn't do filth. Still.
Turk Turon's mention in comments of Evelyn Waugh (pronounced ee-vlin, and yeah, he was a dude) brought to mind EW's son, Auberon Waugh. I remember him as a great wit and a scathing critic in the few journalistic bits I've read of his. Check out his writings on travel and wine review, if you get a chance.
To my delight, Auberon's Wikipedia entry details one of his (in my opinion) great accomplishments in the form of an award for the worst description of a sexual act in a novel. Although I'm a great proponent of sex in real life--bad and otherwise-- icky descriptions of same in novels can be oogy and can utterly dowse a good read, in my humble opinion. Called the Bad Sex in Fiction award, the objective was "to draw attention to the crude, tasteless, often perfunctory use of redundant passages of sexual description in the modern novel, and to discourage it". Fecking finally.
Well done, indeed! In fact, to my delight, the 2007 award was given to Norman Mailer, whose stench-conjuring descriptions of coital interludes in Ancient Evenings sent me into paroxysms in my early 20s, thus rendering me unable to ever crack another Norman Mailer novel again. Call me closed-minded. I can live with that. Anyway, it seemed appropriate that NM's swan song should be met with a proper dressing-down for what surely was a wildly unsexy description of what should have been a sexy act, literally. Dirty old goat.
