submarining 

Being online on a web messenger service but appearing as if you were offline.

Ash: "Are you submarining again?"

Cynthia: "Yes, I don't want to be bothered by all of my contacts, so I answer only those I want to talk to."

submachine gun 

A firearm larger than a pistol, without the range or barrel length of a rifle, or the speed of a true machine gun.

Submachine guns are basically firearms that can be fired in single, burst, or automatic fire with equal ease over short to medium ranges, after which point they become less effective due to inaccuracy.

Submachine guns can actually be rather large, like an MP5SD or FN P90, or small, like a Mac-10. Having akimbo SMGs is becoming amazingly popular in action moves and video games. (though in realistic games and real-life, are not reccomended due to heavy recoil and inaccuracy)

I turned the corner and was immediately pelted with lead. The guy had a submachine gun.

nubmarine 

An idiot gamer who's been playing for quite some time, but still can't manage to get any better than when he first started.

I made this word up myself.
I AM a genious, I know.

That nubmarine just totalled any chance we had of victory.
