To have a screw loose 🔩🧠
Meaning
To be slightly crazy or behave in an irrational way.
Origin
Imagine a time when clockwork mechanisms and early machinery were all the rage. These complex devices, with their intricate gears and screws, were the cutting edge of technology. If a crucial screw wasn't tightened properly or became lost, the whole contraption would malfunction, perhaps even wildly. This mechanical mishap became a vivid metaphor for a person whose mind wasn't functioning correctly—like a poorly assembled machine, they were a bit 'little bit off'. It’s a quirky, tangible image for the intangible idea of mental derangement.
