IDIOMS - ARE JUST A FLASH IN THE PAN

An idiom is an expression that takes on a symbolic meaning when certain words are combined, which is different from the literal definition of the individual words. For example, if   said: 'Don't worry, driving out to your house is a piece of cake.' It would be understood that the expression 'piece of cake' means that it's easy. Normally, we obviously wouldn't associate the word 'cake' when it is on its own as anything other than dessert. But in this context, it's a well-known idiom. So why not throw caution to the wind a try to fill in all the missing words from the common idioms used every day.
