Plasma Pistol 

A weapon in the Xbox game Halo 2 that, when charged to full strength, can deplete a target's shields fully. It is very small and almost useless to use alone, but is one of the most powerful weapons in Halo 2 when used in the right way.

Often used in the Noob Combo.

Player 1: Put down the Plasma Pistol, already! Have pity!

Player 2: Yeah, sure, biyatch.

Plasma Pistol 

The fucking gayest gun in the Halo series.
Shoots pussy ass green blobs.

99% percent of people who use the plasma pistol are noobs, especially when using noob combo, or dual wielding it with a SMG or Spiker (Halo 3).

Plasma Pistol 

A covenant gun in the popular video game Halo 2. It is weak when shot normally, but can lower shields quite effectively when it is charged. You can charge it by holding down the trigger button and releasing it once you find your target. The plasma the gun shoots travels slowly, but locks onto the enemy. The gun is commonly used with the battle rifle as the second weapon. This creates the noob combo. One would shoot a charged plasma pistol and then quickly switch to the battle rifle and shoot once for a kill.

The gamer used his plasma pistol effectively in his noob combo.

Plasma Igniter Pistol

A sidearm that fires short-range bolts of magnetically shaped plasma. On impact, it causes catastrophic thermal and hydrodynamic shock—melting, exploding, and setting the target on fire almost simultaneously. It's a brutally effective close-quarters weapon with a distinctive CRACK-HISSS sound and the lingering smell of ozone and cooked meat. Holstering one is a statement that you intend to leave behind sculptures of slag and ash.

Example: "His plasma igniter pistol didn't leave bullets; it left modern art. A hit to a security drone didn't disable it; the plasma bolt splashed across its chassis, fusing circuits, boiling its battery into an explosion, and leaving a beautiful, glassy crater of molten alloy in the wall behind it. Clean-up was a nightmare."
