unpremeditated
Done without forethought
Unpremeditated describes actions done without planning or forethought—spontaneous rather than calculated.
The word appears most often in legal contexts, where unpremeditated killing may warrant lesser charges than premeditated murder.
More casually, it describes anything impulsive: an unpremeditated outburst, The whole trip was unpremeditated—we just got in the car and drove.
