A common strategy where a player mass builds a many weak units as he can, then rushes the enemy base. Usually works best early in the game. Taken from Starcraft, where often zerglings (really cheap unit that can be built in large droves quickly) would be sent at the start of the game to kill everyone in the first couple moments.
Zerg Player: Ah hahaha! I'm zerg rushing!
Protoss Player: Oh no, my precious zealots are too expensive for me to buy more than one. I'm screwed.
Terran Player: *Flys to higher ground* What a bunch of fags.

The battle tactic when an immense group of poorly equiped or low -level players/minions/characters swarms a much smaller group of well-defended/high-level characters/players and defeats with sheer numbers.
Originated from the game StarCraft, in which if timed correctly you could send a dozen zerglings (lowest-level soldier avalible) into the enemy's base before they could make defenses. Spread to include any battle tactic that involved massive amounts of zerglings to overwhelm the enemy's defense.
"The 2 dozen mid-20 level alliance just zerg-rushed the 60s attacking Darkshire."

"Why bother wasting resources on Ultralisks when 4 dozen zerglings can rip a Protoss base up like tissue paper in a zerg rush?"

The Zerg Rush. A strategy originating from Starcraft used only by the unstrategic. The Zerg Rush consists of mass producing as many Zerg Zerglings or Hydralisks in the shortest amount of time possible and attacking your enemy before he has a chance to do the same to you.

Also sometimes just used as Zerg.
Can be adapted for use anywhere.
I was trying to build some bunkers but after 5 minutes he was ready with his zerg rush. Cheap bastard.

Ok, here's the strategy: I'll hand the ball off to you and everyone else zerg the shit out of them.
