English Idiom
The meaning of this term is derived from Witchery.
During a Witches' Sabbath (or Black Mass), the
head Witch leads a ceremony where, upon tying a mask of the face of Satan to his bare buttocks, he invites all other witches to prove their loyalty by kissing it.
The modern English term, therefore, is used to suggest that a particularly irritating person can be likened to an evil
witch.
