To let the cat out of the bag
- Revelar um segredo ou uma fraude.
A: He let the cat out of the bag.
B: About what?
A: He let the cat out of the bag about the company’s new policy.
If we said "He let his cat out of the bag" or "He spilled his beans", we would face a problem related to the double-entendre.
(1) Literal: He put his pet, a cat, maybe a kitten, out of the bag. How cute!
(2) Figurative [less common; informal]: He revealed his secret.
[It is just to get the conversation shortened. It could be funny too. Beans is a slang term for ecstasy.]
There are other options:
>> He told my secret.
>> He revealed my secret.
>> He let my secret be known / exposed.
>> He spilled the beans. [Idiomatic expression].
