A cheer that has been performed by the Carnegie Mellon Kiltie Band at home football games for many years. Members of the band will line up with cheerleaders on the track and bounce and spin in one direction while spelling the word Bananas. They will then bounce and spin the opposite direction while spelling the word backwards. For some reason, Gwen Stefani has seen fit to use this cheer in a recent single.
Go! Bananas! B-A-N-A-N-A-S! Og! Sananab! S-A-N-A-N-A-B! repeat
