It is a term misused to describe someone who does not like Christmas. In reality, as Charles Dickens said of Scrooge: it was always said of him that he knew how to keep Christmas well, if any man alive possessed the knowledge.
Scrooge's nephew, Fred, has resolved to continue inviting him to Christmas celebrations, regardless of Scrooge's negative attitude towards the holiday. Fred believes in the spirit of Christmas and the importance of showing kindness and goodwill towards others, even if Scrooge does not share his sentiment.
Scrooge was first apprenticed at Fezziwig's warehouse in 'A Christmas Carol'. Fezziwig was his kind and generous employer who had a significant impact on Scrooge's attitude towards money and happiness.
Initially, Scrooge has a disdainful and selfish attitude towards the poor, viewing them as unworthy of help or compassion. However, through the visits of the ghosts in "A Christmas Carol," he undergoes a transformation and learns to show kindness and generosity towards those less fortunate.
Scrooges attitude breaks down when with the Ghost of Christmas Present he sees Tiny Tim and realises that by next Christmas Tiny Tim would die unless the "visions of the future change" . The visions are of course Scrooges attitude to life and charity
Fred loved Christmas and from his conversations with Scrooge it was clear he understood the true meaning

The ghost of Christmas present repeats Scrooges retort of "are there no prisons, are there no work houses"
