Fiddlestick

The violinist had to replace her fiddlestick because it was worn out.

"The new employee seems to use 'um' and 'fiddlestick' a lot during their speeches."

The musician used a special resin to make the fiddlestick less slippery.

"The politician's excessive use of 'fiddlestick' during the debate made her seem less confident and articulate."

"It's not that I don't believe you, fiddlestick, but I need to hear more evidence before making a decision."
