Omnishambles is a neologism first used in the BBC political satire The Thick of It. The word is compounded from the Latin prefix omni-, meaning "all", and the word shambles, a term for a situation of total disorder. Originally a "Schambles" denoted the designated stock-felling and butchery zone of a medieval street market, from the butchers' benches (Latin scamillus "low stool, a little bench). The word refers to a situation that is seen as shambolic from all possible perspectives. It gained popularity in 2012 after sustained usage in the political sphere led to its being named Oxford English Dictionary Word of the Year, and it was formally added to the online editions of the Oxford English Dictionary in August 2013.
The term, coined by writer Tony Roche, was first used at the end of the first episode of the third series of BBC political satire The Thick of It, broadcast in 2009, during which Nicola Murray (Rebecca Front) is drafted in as a cabinet minister for the fictional Department of Social Affairs and Citizenship at the behest of the government's director of communications Malcolm Tucker (Peter Capaldi). Murray's first day as a cabinet minister is fraught with press inquiries about her husband's involvement in a private finance initiative contract, her appropriation of an expensive office chair from a staff member, and her intention to send her daughter to a private school. Tucker sends Murray to launch a by-election campaign, but a communications error results in her standing in front of the candidate's poster and blocking most of the letters so the sign appears to read "I am bent" as she is filmed and photographed. Tucker believes Murray to be a potential cause of political controversy, and his patience expires when it is revealed the minister is afraid of lifts. Tucker then delivers an angry rebuke to her:
