Take two sweets and take a bite of the big secret. What does this mean?

"Eat two sweets, one mouthful a big secret" is a suggestive statement, which means there is a secret to keep, and only two people know it. This expression is usually used to pass secrets between two people and ask them to keep secrets. The source of this statement may be that candy is usually a snack that children like to eat, and no one will disturb them when eating candy, so two people can use this statement to hint at each other when sharing secrets. It should be noted that this statement is only a metaphor and cannot be used for real secret transmission. In real life, if you need to pass important secrets, you should use safer and more reliable methods, such as face-to-face communication or encrypted communication tools.
