Why is it called a Zerg rush?

A "Zerg rush" is a term originating from the real-time strategy game "StarCraft." It refers to a swift and overwhelming attack strategy employed by the Zerg race, characterized by mass-producing cheap units and swarming the opponent before they can adequately defend themselves. The term "zerg rush" comes from the name of the insect-like alien race in the game known for their ability to rapidly reproduce and overwhelm foes. This tactic's effectiveness lies in its sheer numbers and speed, often catching opponents off guard and pressuring them into a defensive stance. The term has since transcended gaming, becoming synonymous with any rapid, mass assault strategy.
