Explanation of Secret Santa:

Person A will buy person B a present but person B will not know who person A is till the day. Person A will then be the Secret Santa for person B. But person A will also receive a surprise present from person C. So person C will be person A’s Secret Santa. As it is said, presents from Secret Santa will ensure you the good luck for the whole year. People also use Secret Santa to confess or propose!
