Fiddlestick

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

"I'm not quite sure how to answer that question, um, fiddlestick, I'll come back to it later."

"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."
