The first known cheer from the sidelines, heard at a Princeton University football game in the early 1880s.  Referred to as a locomotive because of its slowly building noise, the cheer is still used at Princeton:

Hip, hip! Rah, rah, rah! Tiger, tiger, tiger! Siss, siss, siss! Boom, boom, boom! Bah! Ah! Princeton! Princeton! Princeton!

According to Ask a Male Cheerleader (who knew?), the cheer was adapted from the marching chant of the Seventh Regiment of New York City, which obviously made an impression on the college boys as it passed through Princeton on its way to Washington, D.C. to fight in the American Civil War.
