Political words: twitterati, chillaxing and eurogeddon
The Westminster village and journalists use words such as civet, chillax, grexit, twitterati and eurogeddon.
But they may leave some of the public behind who have no idea what such words mean, and probably will not find many of them in the dictionary.
Adam Fleming asked the public - including a passing BBC correspondent - to pick a word and see if they could explain them.
Shadow chancellor Ed Balls reportedly told the prime minister to "chillax" and have another glass of wine which led to David Cameron referring to him as a "muttering idiot" in PMQs.
