Un coup de Jarnac

Meaning: An unexpected decisive stroke, delivered within the rules but not quite sportingly.

Language: French

Literally: A Jarnac blow

Category: Daily Life

Origin: In a judicial duel of 1547 before Henri II, Guy Chabot de Jarnac won by an unforeseen low cut to his opponent's knee. The stroke was legal, which is exactly why the phrase carries ambiguity rather than simple condemnation.
