Balls up

nounShop talkMaritime

A completely botched job, disastrous situation, or severe operational mistake.

This describes a severe mess or failure in shipboard operations, from a tangled mooring line to a major navigational error. While a popular maritime myth claims the phrase comes from hoisting warning spheres into the rigging to signal a plague or mutiny, it actually originates from standard working slang for a tangled mess. Crews use the phrase to call out incompetence or a poorly planned maneuver.
