let the cat out of the bag Tiết lộ bí mật Meaning: If you let the cat out of the bag, you let someone know a secret. Origin:Possibly related to the fact that in England in the Middle Ages, piglets were usually sold in bags at markets. Sometimes, someone would try to cheat a buyer by putting a cat in one of the bags instead of a piglet. And if someone let the cat out of the bag, the fraudster's secret was revealed.

For example:

• We'd planned a surprise party for Ngọc, but some guy she works with let the cat out of the bag, so now she knows.
  
• Don't forget that this is a secret, so whatever you do, don't let the cat out of the bag.
  
  

After Liên let the cat out of the bag, everybody laughed we all knew they ran after it
