How it's used

This idiom relies on the biological fact that chickens do not urinate separately from their droppings, making the event impossible or at least unseen. It is used to express genuine surprise at an event that defies expectations or normal patterns. It carries a slightly humorous and informal tone, often used when someone does something completely out of character.

Examples

He actually offered to pay for the meal, that is incredibly rare!
This situation is practically unheard of, very rarely seen.

Common phrases

truly a rare occurrence

Common mistake

Do not use this in formal or professional settings, as the literal imagery is considered crude or vulgar by some speakers. It is strictly for casual conversation among friends or peers.
