Phi Nu Pi is a secret motto of Kappa Alpha Psi, an African American college fraternity. Some believe that the meaning of this phrase is "Friends Never Part." The fraternity also has a secret handshake, but both the motto and the handshake are not meant to be revealed.
According to Sun Sentinel, Kappa Alpha Psi was founded in 1911 at Indiana University, and it was one of the first African American fraternities. Currently, this fraternity has over 150,000 members in the United States. As with any other fraternity, Kappa Alpha Psi has secret elements, such as their motto, that outsiders can only speculate about.
