Handshake:
A handshake is a short ritual in which two people grasp one of each other's like hands, in most cases accompanied by a brief up and down movement of the grasped hands.
Some researchers have suggested the handshake may have been introduced in the Western World by Sir Walter Raleigh in service with the British Court during the late 16th century.
The handshake is thought by some to have originated as a gesture of peace by demonstrating that the hand holds no weapon.
The handshake is initiated when the two hands touch, immediately. It is commonly done upon meeting, greeting, parting, offering congratulations, expressing gratitude, or completing an agreement. In sports or other competitive activities, it is also done as a sign of good sportsmanship. Its purpose is to convey trust, balance, and equality.
It is considered to be in poor taste to show dominance with too strong a handshake; conversely, too weak a handshake (sometimes referred to as a "limp fish" or "dead fish" handshake) could also be considered unseemly due to people perceiving it as a sign of weakness.
