The term CRATCHIT KID refers to two characters from Charles Dickens' novel 'A Christmas Carol'. The first character is Tim, a young boy who works as a clerk for Ebenezer Scrooge. The second character is Tiny Tim, Tim's son, who is a sickly child with a positive outlook on life. Both characters are beloved by the Cratchit family and serve as a reminder of the importance of family and kindness during the holiday season.
