This word is used as a metaphor. Being as such it has a message to deliver as such. And this message should suffice as a message to grant somebody a warning. For example here when someone says that the talks were cloudy between the two rivals. This word is also used between two lovers. For example one can say that one's relation with her lover is cloudy. In essence this word is double edged.
