Where did the phrase your as big as a minute come from?

The phrase "you're as big as a minute" is an idiomatic expression primarily associated with British English, often used to humorously indicate that someone is very small or insignificant. Its origins are somewhat unclear, but it is thought to date back to the 19th century. The phrase plays on the idea that a minute, as a unit of time, is fleeting and diminutive, thereby emphasizing the smallness of the person being addressed. It reflects a playful use of language rather than having a specific historical origin.
