A fiddlestick is a bow used for playing a stringed instrument, especially a violin or fiddle. But more often, it's used as an exclamation of annoyance or disbelief, like saying 'nonsense!' or 'rubbish!'. Think of it as a polite way to express disagreement. Unlike stronger curse words, it's mild and somewhat old-fashioned. Imagine your grandma saying it when she hears something silly. It conveys skepticism or mild frustration.
