How did Humbug describe himself?

From the text:

"NONSENSE! Everyone loves a Humbug," shouted the Humbug. "As I was saying to the king just the other day——"

"BOSH!" replied the Humbug. "We're an old and noble family, honorable to the core—Insertions Humbugium, if I may use the Latin. Why, we fought in the crusades with Richard the Lion Heart, crossed the Atlantic with Columbus, blazed trails with the pioneers, and today many members of the family hold prominent government positions throughout the world. History is full of Humbugs."
