nube combo
When playing Halo2, a combination of the plasma pistol and another gun, typically the battle rifle. The cheap, but rather effective way to get kills. Often used by a weaksauce, nubbo, nube, nub, you get the picture.
I got a nube combo over at the crash-site. 
Allright, who's using the nube combo?
Damn, I just got owned by the nube combo!
