a grenade that sticks to any surface and usually explodes with plasma energy instead of fragmentation from a regular grenade hence its name. No this type of thrown weapon is not only in Halo nor was it "invented" from Halo. Many sci-fi shooters have this type of grenade.
p.s. can be referred to as plas for short.
Joe: Hey dude, you choosing frag or plas?
Bill: Eh, I'm a have to go with the plasma grenade.
Joe: Why? Because it started in Halo? I know how much you like that game.
Bill: No, I prefer to use it because I'm more accurate at getting my targets with it than a bouncing fragment grenade. Also it did not originate in Halo, it is has been around also in science fiction movies.
Joe: Okay, I was wrong let's just play the game.
Bill: Cool then, lets.
