carte blanc
term to describe the short-term separation of a set of lovers. when 'carte blanc' is called by either person, both of the people in the relationship are free to do whatever, and more so whoever, they wish. it is different from 'talking time off' or a separation, break-up, etc... in that the possibility of negative consequences are slim.
My girlfriend called carte blanc this week, so I can have fun fucking whoever I want, and she will do the same.
