Black Friday.

Black Friday is the day following Thanksgiving Day and is known to be the biggest shopping feast in the US, with most retailers offering big discounts. It also marks the beginning of the Christmas shopping season. The phrase was coined in the 1960's, but it was during the 1990’s and early 2000’s that it became widespread. Black Friday is now a big shopping day in many countries outside the US as well. Three days later comes Cyber Monday, which is the same concept but for e-commerce.
