In an interview with NBC10, he said that the term was coined by the Philadelphia Police Department after the city was overrun with fans coming to town for the Army-Navy game. With the game typically held on a Saturday, the city was full of rowdy fans on Friday — creating chaos and overrunning retail stores.
"The day before, people are rushing into Philly for the game," Farley said. "The police are overwhelmed. The idea of this day — that was a very bad day for the cops — became labeled Black Friday."
