n black flag
A flag made of black cloth indicating some deadly or nefarious purpose of the
bearer, for example, pirates and the Jolly Roger and the Royal Navy flag indicating

n Black Friday
Used in reference to a variety of calamitous events through history occurring on
a Friday and perhaps originating from the time Good Friday was referred to in
Britain as ‘Black Friday’ because the clergy wore black. There has been a series
of Black Fridays in US stock market history. See also Black Monday and Blue
Monday. Apparently, the rest of the week portends less risk of disaster although
the ‘Black Tuesday’ of 29th October 1929 was the worst day of the 1929 Wall Street
crash, the fall on Wednesday 23rd October 1929 referred to as ‘Black Wednesday’
was significant and the stock market panics in the US on Thursday 9th May 1901
and Thursday 24th October 1929 are each referred to as being a ‘Black Thursday’.
Wednesday 16th September 1992, the date when the Conservative government
in the UK ignominiously pulled out of the European Exchange Rate Mechanism
or ERM, is also referred to as ‘Black Wednesday’. The term ‘Black Saturday’ has
also been coined.
