Blah blah fishcakes
Watching Newsnight just now, I heard Boris Johnson use the curious phrase ‘blah blah fishcakes’ to mean, in a somewhat flippant way, et cetera. It wasn’t the first time I’ve heard this expression. A friend of mine called Henry used to use it, back in the 80s. As it happens, he had been to Eton, just like Boris. Is it a piece of Eton slang?
