I've had a superior barrage me with questions, faster than I could possibly answer them. It was incredibly adversarial. I was kinda stunned, to be honest, and i took a beat to collect my thoughts. Gave him a brief, mostly involuntary wide-eyed stare, took an audible breath, and set about deliberately answering his questions in an order that made sense. The rest of our meeting went smoothly.

When a coworker is acting like an ape, a moment of silence can inject some calm into the situation.
