The map ran out, but your mouth still promises you know the way.
means A situation so new that no prior experience, precedent, or guide exists to show you what happens next.
from Straight from old sea charts: mapmakers drew coastlines and depths only where ships had actually sailed and measured. Beyond that, the paper went blank, or carriers scrawled warnings like 'here be dragons.' To sail into 'uncharted waters' was to leave the last known depth-marks behind and navigate by guesswork, stars, and nerve. By the 1800s the phrase had drifted ashore into general English, used for any venture — business, science, personal life — where no map, precedent, or expert had gone before you.
