What rhymes with supercalifragilisticexpialidocious?

Nothing rhymes with the whole Word. In the Mary Poppins song, they only rhyme with the "ocious" part to get: atrocious, precocious, and ferocious.

In theory, you could use the long-winded phrase: "Super calloused fragile mystic hexed with halitosis."
precocious

atrocious
