Fiddlestick

"The error in his speech was just a fiddlestick, he continued on with the presentation."

"I let out a frustrated fiddlestick when my computer crashed for the third time that day."

"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."
