     Have you ever heard someone use the phrase"once in a blue moon"? People use this expression to

describe something that they do not do very often. For example, someone might say that he tries to

avoid eating sweets because they are unhealthy, but will eat chocolate"once in a blue moon". Or

someone who does not usually like to go to the beach might say " I visit the shore once in a moon."
