Jiggery-pokery is a British term meaning "underhand or deceitful behaviour".
Behind the scenes
- While Harry seemed to be merely making up nonsense spells, the appearance of the spell in the title Jiggery Pokery and Hocus Pocus, described as containing "mischief-making spells," suggests that it could in fact be a real spell (though it presumably does not set hedges on fire).
