How it's used
Describes someone who lacks the ability to keep a secret or maintain confidentiality. It implies a lack of discipline in speech rather than malicious intent, though the result is often the same. It is frequently used as a warning to others before sharing sensitive information.
Examples
He has a loose tongue, definitely do not tell him.
You are so loose-lipped, how can anyone trust you?

Common phrases
very loose-lipped
Common mistake
Do not confuse this with 口密, which describes someone who is tight-lipped and good at keeping secrets. Learners sometimes mistakenly use it to mean someone who talks too much in general, but it specifically refers to the inability to keep a secret.
