Fiddlestick

"I responded with a polite fiddlestick when he suggested we take his idea to the boss."

"He considered the typo in the email to be a fiddlestick and didn't bother to correct it."

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

"After hearing the news, he stood there for a while, looking for a response, until finally saying 'fiddlestick' and walking away."

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