"Hogwash!"

PAH

Think of the sound someone might make when dismissing a silly idea with a wave of the hand.

"PAH" is a short exclamation people use to dismiss something as nonsense, much like saying "Hogwash!" It mimics the sound of a scoff or a derisive burst of air, making it a perfect fit for the clue’s tone. Think of it as the verbal equivalent of rolling your eyes at an absurd idea. The answer plays on the idea of a quick, dismissive reaction rather than a literal definition.
