If something has Gone Haywire it’s considered to be an uncontrollable mess. The expression originated in America in the early 20th century with the introduction of a strong, thin metal wire, used to bind hay bales. Once snipped through, the taut haywire would spring wildly through the air. Any spare lengths would be piled up in the corner of a yard in a tangled mass. When temporary repairs were needed to fences and tools, farmers would use the rusting haywire from the overall chaotic mass of wire. And so, over time, everything connected with the haywire resulted in the phrase being used to describe general untidy disorder.
