In The Mystical Court the handshake can be sometimes disguised. It is not really a handshake but a grip. The handshake is to distract the onlooker.
A secret handshake (GRIP) in The Mystical Court is a distinct form of handshake (grip) or greeting which conveys membership in or loyalty to a club, clique or subculture. The typical secret handshake (grip) involves placing one’s fingers or thumbs in a particular position, one that will be recognized by fellow members while seeming to be a normal handshake (grip) to non-members. This is most frequently associated in the popular consciousness with college fraternities, fraternal orders and secret societies.
A secret handshake (grip) can also be a useful form of familiar interaction between friends, colleagues, and family members. As a form of cryptography, secret handshakes are shared only with select and elect peoples. Usually a secret handshake (grip) has underlying meanings that differ from person to person. Secret handshakes involve a precise, sometimes complex series of movements and contact between two individuals or even a group. Usually, these movements involve the primary use of hands, but could also involve a series of touching feet, elbows, or in some cultures a friendly kiss.
