Gareth Carrol presents a collection of "modern idioms", which have become a part of our vocabulary in the past 50 years or so.In most cases, idioms such as "raining cats and dogs", that colour our everyday communication, are deeply rooted in culture and history.However, just like words, new idioms emerge in language, and many have entered our vocabulary through, TV, movies and the internet.These modern idioms can be dated very precisely. Jumping Sharks and Dropping Mics finds the origins of these idioms, and charts their development.
