Metric Assload, measurement: 1.Used to describe a whole lot when you don't feel like giving the exact large number of something. Ex.: "So what? My solo has a metric assload of bullets left for his rifle. It's not a big deal." 2.An unfortunately large number of monsters, mooks, or other antagonists that the players have somehow just blundered into. Syn. "Wall-to-Wall", "Packed in like sardines". Ex: "So the Paladin gets tired of the party arguing, and kicks the door into the leader of a metric assload of orcs that're in the room beyond."
