 The 12th Man uses a variety of school yells , rather than cheers , to support Aggie teams . Each year the student body elects five students to serve as the Yell Leaders . At midnight before each home football game at Kyle Field or at a predesignated location at away games , the fans gather together to practice the yells for the next day 's game . Led by the Yell Leaders , and the Fightin ' Texas Aggie Band , the Twelfth Man files into the stadium to participate in Midnight Yell Practice to practice yells , sing the War Hymn , and joke about their opponents . At the conclusion of the yell practice , the stadium lights are extinguished and fans kiss their dates . This is also done as practice , because Aggies are expected to " mug down " , or kiss their dates , every time the football team scores on the field . Sports Illustrated named Midnight Yell as one of the " 100 Things You Gotta Do Before You Graduate . "
