"...If he had been an English lad, he would have been off to his sweetheart long before this, without saying with your leave or by your leave; but being a Frenchman, he is all for Aeneas and filial piety,—filial fiddle-sticks!"

The lovers were fiddlesticks, he thought, collecting it all in his mind again. That's fiddlesticks, that's first-rate, he thought, putting one thing beside another. But he must read it again. He could not remember the whole shape of the thing.
-- Virginia Woolf, To the Lighthouse, 1927
Fiddlesticks came to English in the 1400s from the late Middle English term fidillstyk.
