How it's used
This expression specifically targets the lack of a filter between one's thoughts and speech. It is often used as a warning or a critique of someone who habitually blurts out offensive or inappropriate comments without considering the consequences. Unlike simply being rude, it implies an inability to control the flow of speech even when the situation clearly calls for silence.
Examples
He is foul-mouthed and always says unpleasant things.

Common mistake
Do not confuse this with simply being talkative, which is usually expressed as 多口. Being talkative is a neutral or slightly annoying trait, whereas being 把口唔收 carries a strong negative judgment about the person's character and lack of social awareness.
