I wish I knew what this is all about.
Never played Starcraft or anything.
When you're playing Zerg, you must first build a spawning pool before you are able to spawn zerglings, the most basic of zerg combat units. If executed properly against an unprepared opponent, a zerg rush can either devastate or defeat your opponent. They're usually classified with names like 6-pool, 10-pool, 13-pool, etc., but in this situation someone thought that the numerical prefix means you have to construct that actual number of spawning pools.
Hilarity ensues.
