Hocus-pocus is used in Spell.
Brewer’s Dictionary of Phrase and Fable seats Hocus Pocus as the words a conjuror utters when he performs a trick — often derived from Hoc est corpus, or from Ochus Bochus the northern magician invoked by jugglers. A named Hocus Pocus in that trick-spell speech, not a bare nonsense dump alone.
