How it's used
This idiom vividly paints a picture of someone who talks big without cleaning their mouth, implying they make empty promises or exaggerated claims that they cannot back up. It is strictly used to criticize someone for being unreliable or a braggart rather than just a casual chatterbox. The phrase carries a dismissive tone, often used to warn others against trusting the person's words.
Examples
He is always boasting, don't believe him too much.

Common mistake
Do not confuse this with simply chatting or hanging out, which is often called 吹水. Adding 唔抹嘴 changes the meaning from a neutral social activity to a negative character judgment about someone's honesty.
