From Furphy (“a surname”).
The firm of Furphy and Sons (still in business today[1]) manufactured and supplied water carts[2] to the Australian Imperial Force in Egypt during World War I. Soldiers stood around these and talked, exchanging rumours and news. The manufacturer's name, which was emblazoned on the carts, was soon adopted for unreliable information or speculation. [3]
