Car blanch is J.C.'s bastardization of the French 'carte blanche'. Meaning: Unrestricted power to act at one's own discretion; unconditional authority
Usage: Rather than observe military custom and courtesy, J.C. chose to send an email, questioning the decisions of leaders, car blanch. In his email, replete with its own grammatical errors, he criticizes them for not checking grammar.
