Georgia Institute of Technology
Georgia Tech students hold a heated, long and ongoing rivalry with the University of Georgia, known as Clean, Old-Fashioned Hate. The first known hostilities between the two institutions trace back to 1891. The University of Georgia's literary magazine proclaimed UGA's colors to be "old gold, black, and crimson". Dr. Charles H. Herty, then President of the University of Georgia, felt that old gold was too similar to yellow and that it "symbolized cowardice". After the 1893 football game against Tech, Herty removed old gold as an official color. Tech would first use old gold for their uniforms, as a proverbial slap in the face to UGA, in their first unofficial football game against Auburn in 1891. Georgia Tech's school colors would henceforth be old gold and white.
National Football League rivalries
The Browns–Ravens rivalry in the AFC North began with the resumption of the expansion Browns' franchise in 1999, the direct result of the Cleveland Browns relocation controversy. The rivalry between the Browns and Ravens was more directed at former Browns owner Art Modell than the team itself, and has, by most Raven fans, been simply considered a divisional game in Baltimore, but features an intense hatred in Cleveland for the Ravens. Unlike the other two rivalries, this one is more lopsided: with the Ravens leading in the series 29–9.
