Cut and pasted from Wikipedia:
Humbug is an old term meaning hoax or jest. In modern usage, the word is most associated with Ebenezer Scrooge, a character created by Charles Dickens. His famous reference to Christmas, "Bah! Humbug!", declaring Christmas to be a fraud, is commonly used in stage and television versions of A Christmas Carol and also appeared frequently in the original book.
