a player in a FPS (or any other multiplayer game which involves fast action and guns) who sits back as other players duke it out in a firefight, and makes an appearance after the victor of the duel is left with a little amount of health and kill him/her for an easy kill. Much like a janitor cleans up after a mess.
Dude, its no fun playing Halo with you anymore because all you do is janitor with your assault rifle.

When someone (in a first person shooter game) appears at the last second and steals my kill because he somehow put the last bullet into the noob I've been shooting at.
In Halo 2 - when anyone steals your kill right before you were about to put the final bullet in someone's head or heart. Hence the name: Janitor = Anyone who comes in and cleans up the "crap" they never started.
