Loki's wager

Loki's wager is the insistence that because two or more categories exist as poles on a spectrum with a grey area in the middle, the distinction between the two cannot be defined.35), the Norse trickster god Loki made a bet with the dwarf Brokkr in which he wagered his head.After a discussion on the matter, while parts of Loki clearly belonged to the head or the neck, neither side could agree exactly where one ended and the other began.Loki therefore kept his head indefinitely,[1] though afterwards his lips were stitched shut by Brokkr as punishment for using tricky wordplay.[2] Loki's wager, therefore, is a situation in which a person unreasonably insists that a term cannot be defined, making it impossible to discuss.
