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.
East Carolina–NC State rivalry
The most prominent sport in the rivalry is football. The two teams began competing against each other in 1970. The football series between the two teams was suspended in 1987. Jim Valvano terminated NC State’s scheduling of East Carolina after Pirate fans tore down goal posts and the playing surface at Carter–Finley in 1987. NC State’s athletics administration had publicly warned ECU and Pirate fans after two consecutive years of minor vandalisms to the stadium. 
The schools would not meet again until the 1992 Peach Bowl. In 1996, the two schools met in Charlotte's Bank of America Stadium rather than on either school's home field. In 1997, the North Carolina Legislature proposed a bill demanding that UNC–CH and N.C. State must play East Carolina on an annual basis. This would officially revive the series between East Carolina and N.C. State.
