The origin for the “high-five” is claimed by Derek Smith of the 1980 NCAA champion University of Louisville basketball team
Smith was quoted in The New York Times, The Sporting News, and other publications as saying that he and his teammates Wiley Brown and Daryle Cleveland wanted something "a little odd
" The high-five was created and fine-tuned during preseason practice and introduced to the nation on TV in 1979
