Spill the beans

When we say someone “spills the beans,” it means they reveal a secret or disclose information that was meant to be kept confidential. It’s like accidentally tipping over a container of beans and revealing what’s inside when you weren’t supposed to. Imagine a group of friends planning a surprise party for someone, and one of them accidentally “spills the beans” by revealing the secret to the person being surprised. In this case, they let out information that was meant to be kept hidden or unknown.
The Idiom “spill the beans” is often used in informal settings to describe situations where someone unintentionally discloses something that was supposed to be a secret. It can also be used humorously when someone reveals a surprise or a piece of information prematurely.
