That is a fictional nonsensical phrase created by Lewis Carroll in his poem "Jabberwocky" from Through the Looking-Glass. It is meant to evoke a sense of the absurd and whimsical nature of the poem.
The King of Lilliput is King Augustus and the Queen is Queen Griselda. They are fictional characters from Jonathan Swift's novel "Gulliver's Travels."
In "Gulliver's Travels," Lemuel Gulliver is the main protagonist and hero who goes on various adventures to different lands. The villains in the story are typically the inhabitants of these lands, such as the Lilliputians, Brobdingnagians, Laputans, and Houyhnhnms, who often represent different aspects of human nature or society that Jonathan Swift was critiquing.
