   “Our forecast calls for a return of summery weather in the 80s this weekend, so we actually can get out and mow down those weeds without having to inhale clouds of dust.”

2. To kill or slaughter, or to injure by knocking down, especially in large numbers and in a ruthless manner.

   “[T]heir machine-gunners mowed down wave after wave of counterattacking Chinese.”

   “The simplest rejoinder to all of Daenerys’ justifications is that this bloodshed could have been avoided. She was given a moment to choose, and she chose blind vengeance, the kind that eliminates any benevolence she hoped to bring to the seven kingdoms by burning it right out of the minds of anyone who saw her astride Drogon, mowing down men, women, and children with abandon.”
