not a snowball's chance Hello erverybody! "not a snowball's chance in hell" is the complete expression. Is this expression very common? Who use it? First I only wanted to ask that question now I'm writing more and so I need a correction. I still lack words and the correct use of tenses and expressions is still difficult. I chanced to read the above-mentioned expression recently and I reminded that I heard it many years ago. It happened in a conversation with a woman who was talking about her childhood. It was a remarkable story. As remarkable that I'm able to remember this expression after so many years. I always forget my vocabulary - even the simple words. However this expression I remember.
