Black Friday is not another bad hair day in Wall Street. It’s the term used by American retailers to describe the day after the Thanksgiving Holiday, seen as the semi-official start of Christmas shopping season.

Davis contrasts two meanings of “Black Friday”: the finance-world sense of a market calamity and the retail-world label for the post-Thanksgiving shopping surge. By joking that it is “not another bad hair day in Wall Street,” he signals that the phrase can mislead outsiders into thinking it denotes a financial crisis, then clarifies its mainstream American usage as the kickoff to Christmas shopping. The quote functions as a brief piece of cultural translation, highlighting how commercial calendars and media shorthand create terms that travel internationally but carry different connotations depending on context.
