In one of his regular anti-gay columns (too drab to link to here), John Derbyshire of the National Review recounts the following conversation conducted with Martin Gilbert about his biography of Churchill:
Gilbert: ... When Churchill was 20 and a young soldier, he was accused of buggery, and you know that's a terrible accusation. Well, he ended up prime minister for quite a long time.
Lamb: Why was he accused of buggery, and what is it?
Gilbert: You don't know what buggery is?
Lamb: Define it, please.
Gilbert [clearly flustered]: Oh, dear. Sorry, I thought the word would — buggery is what used to be called "an unnatural act of the Oscar Wilde type", is how it was actually phrased in the euphemism of the British papers...
In America, we call it ass-fucking.
