Zeroing 

When you're smoking weed and you take a hit and you hold in 100% of the smoke from the inhale, exhaling *zero* smoke from the hit. Done in order to get maximum effect from the weed. Requires great skill and is worthy of respect from other smokers.

"Yo I was ripping a B with Joey Fatone the other day and he was totally zeroing every time ... insane!"

zerging 

n. Using massive amounts of weak, or generic units, to attack an enemy.
Used widely in PlanetSide, to describe massive amount of soliders that spawn in a tower, and then attack a base.
It comes from the word wordzerg/word. Zergs in Starcraft were able to produce large amount of units very quickly.

I hate, when base assault comes down to zerging
