Bards Cant

A subtle language that uses a lot of metaphors and similes to speak in plain sight to other bards for purposes of espionage or entertainment.
Example conversation:
Bard 1: "Hark, here approacheth the foulest beautiful dawn in the winter weather" (Here comes a cute asshole) Bard 2: "Aye, such the dawn approach to take back its light shining, for many deeds remain unshone." (Yeah I'm here for my money).
