Used in gaming for a attack of many unskilled units on a difficult target.
From "The Last Starfighter" a movie from 1984 which had a villian named "Xur" or "Zur". (The villian utilized massed forces which would swamp defenders and the heros could defeat in numbers) The benefit of this strategy is a superior unit or units can only eliminate a certain number of attackers at the same time allowing enough of the attackers to survive, do damage and hopefully defeat the defender or get around it. A classic "horde" or "wave" type attack.
"We Zurged the guardian of Orion with our fleet of fighters" or "We Zurged Stormwind with 250 low levels to get inside the gates"
