The act of stopping mid stream while urinating to pop a squat. Often necessarily executed in haste as a result of blindly trusting a fart that has gone awry while taking a piss. There is no time to flex the stream closed. It must be manually pinched off and involves the act of shuffling awkwardly while simultaneously attempting to put the seat down and drop trou'. SHALL only be attempted by seasoned professionals.
Dave: "That was a long piss. You good bro?"
Ryan: "I was mid stream when the Chinese food hit, I had to pinch and pivot to avoid catastrophe."

Sarah spent the weekend cleaning the bathroom as a result of a poorly executed pinch and pivot by Scott.
