Fiddlesticks!

Hi,

<"What do you want with the tinder box?" asked the soldier.
"That's got nothing to do with you!" said the witch. "You've got your money all right. Just give me the tinder box."
"Fiddlesticks!" said the soldier. "You tell me straight off what you mean to do with it, or I'll out with my sword and cut your head off.">
(from Hans Andersen Forty-Two Stories [1930], translated by M. R. James)

Do people still use the expletive?

Thanks.

It might be used in humor, but not seriously.

Fiddlesticks is a charming expression from the 19th c. It is no longer used in normal everyday conversation, unless you want to use it as an antiquated expression for comic effect

I see, thanks.

My old boss who is British used the term fiddlesticks when something didn't go quite right. I always found it amusing when she said it. This was within the past 2 years.

It's a good way of stopping yourself from saying 'fuck' (excuse my French!) when in unfamiliar company.

Similarly, sugar instead of s***.
