Poetic License…

a permit to say strange things in strange ways.

It’s not quite Bond’s License to Kill,
but, sometimes — merely by using words —
one can deceive people into thinking
that conveying meaning is one’s principal goal.

It’s not a Double-Oh License to Kill,
but it does let one write in secret ciphers,
with each reader providing their own key.

What mayhem might be unleashed by one operating under such a license?
