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.

The rivalry began in 1899 and was played almost annually up until 1929. It was renewed in 1940 on an annual basis until 1955, with only a three-year break from 1943–45 for World War II. After that, the series became much more intermittent. They have faced each other in two bowl games; the 1998 Peach Bowl and the 2007 Chick-fil-A Bowl.
