Nice list ... though it's a bit to literal in some cases, and a bit "proper" in others ... Some suggested additions ...
PvE: Player versus Enemy.
PvP: Player versus Player.
F2P: Free to Play.

Toon: The player character you use in game.
Alt: A second or third etc. Character that you don't use as often.
Main: Main Character that you use regularly, generally used to describe the character that has the most gear/resources/money/highest skills etc.
Spam: Can be used to describe any large amount of on screen effects, or items, such as "FAW Spam" describing multiple ships using this power. Or "Torp Spam" for multiple Torpedos. Can also be used to describe low level enemy ships in certain larger zones.
Pets: Any Ship or Fighter than can be equipped into a ships Hangar. Also used to describe the AI controlled component of ships that "split" such as the Galaxy-X or the Haakona Warbird
DoFF, DOFF: Duty Officers
BFAW, FAW: Beam Fire at will (the more common used, abbreviated version)
BO: Beam overload (the more common used, abbreviated version)
HYT: High Yield Torpedo (the revers of the one you posted, usually refering to the warhead, rather than the Bridge Officer ability)
ESTF: Used for pretty much any Elite difficulty PvE queued Team map

NM: Never Mind
NP: No problem
Vape: vapourize (frequebtly used in relation to PvP)
Tard: Derogatory term or Insult (as in "Scimitard" or someone who fly's a Scimitar Dreadnought badly)
PVE most of the time refers to Player vs. Environment (usually referring to missions you can queue for through the PVE window).
ESTF (Elite Special Task Force) are Elite Borg STF missions that provide Omega marks.
EPVE refers to any of the PVE (aside from STFs) that are elite.
(EDIT) Also, the term tard is short for the derogatory, and insulting term retarded, which refers to ones with less mental abilities. It has been used with the name of Scimitars to insult the pilots of them for different reasons. Sometimes it is used to insult pilots of Scimitars that make mistakes, or have trouble flying them. However, it is also used to insult Scimitar pilots that upset others that don't like the Scimitars getting higher DPS that they cannot get, or just because the Scimitar pilots didn't do what they wanted them to.
Let me make sure I understand this. You write a childish, whining post about the OP's comment being childish and whining, and expect to be taken seriously?
Noob / Nub: New Player Unfamiliar with Protocols (bad version).
Generally noob doesn't always mean new player, hence why we have two words, newb and noob, with newb meaning a new player that hasn't learnt something yet and noob meaning any player who does something stupid when they should know better.
