What is "omnishambles"

n. (context UK informal chiefly politics English) A situation that is bad or mismanaged in every way.

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.
