How it's used
Used as a protective verbal charm to ward off bad luck when someone mentions a misfortune, death, or disaster. It functions similarly to knocking on wood in Western culture, effectively cancelling out the negative energy of the preceding statement. It is considered quite blunt and is usually reserved for close friends or family members who have said something particularly ominous.
Examples
Shut your mouth, don't say such unlucky things.
Why are you saying this? Seriously, shut your mouth.

Common mistake
Avoid using this phrase in formal settings or with people you do not know well, as it can sound aggressive or rude. It is strictly a colloquial reaction to bad omens and should not be used as a general command to be quiet.
