Here's a brief glossary of terms for Star Wars: Galaxy of Heroes (SWGoH)
3PAC or Chewpio - Threepio & Chewie. Oh dear.
AdRad - Admiral Raddus. It's not a trap.
Badstila or Nasty Basty - Bastila Shan (Fallen). Where Revan leads, she follows.
Bando - The Mandalorian (Beskar Armor). He can bring you in warm...
BKM - Bo Katan (Man’dalor). Aka Bodalor. Aka Queen Bo.
Book Boba or Library Boba or BFSoJ or Dad Bod Boba - Boba Fett, Scion of Jango. His kit is every bit as good as the Book of Boba Fett TV show.
CAT - Commander Ahsoka Tano. She's SO good.
CG - Capital Games. They make the game.
CLS - Commander Luke Skywalker. Tauntaun not included.
CUP - Coruscant Underworld Police. Best goddamn character in the game.
CWC - Clone Wars Chewie. 3 shards!
DDK - Droideka. I dunno why.
DR or Dr. Evan - Darth Revan. The real revan used two lightsabers.
DS - Dark Side (usually with a number and letter, such as DS2A, which would be Dark Side sector 2, node A)
DTMG - Dark Trooper Moff Gideon. Dark the Magic Gathering?
EP - Emperor Palpatine. Let the hate flow through you.
Farty or Sortie - 5OR-T. She's legitimately great, but no one will believe it because she's the one of the only original IP characters in this entire game, and she's based on that stupid casino planet from the sequels but has the OR tag for "reasons" and if CG wanted to add a new droid character 4LOM was RIGHT THERE. Hashtag Justice44LOM.
FO - First Order. The first order of first order is you don't talk about first order.
FOO - First Order Officer. His ship is colloquially referred to as the "FOO Fighter."
FOE or FOX - First Order Executioner. I swear all these first order guys have acronyms.
FOST - First Order Stormtrooper. See?
FOTP - First Order TIE Pilot. And they just get longer.
FOSFTP - First Order Special Forces TIE Pilot. Now it's just getting ridiculous.
FOSFTFFC - First Order Special Forces TIE Fighter Fleet Commander. I made this one up.
GAS - General Anakin Skywalker. Also a thing I have that my wife hates that I have it, especially when I have it during dinner.
GBA - Geonosian Brood Alpha. Best bug of the bunch.
GC - Galactic Challenge. It challenges the galaxy. You can tell it apart from the other GC because this one is in “events” and that one is in “Galactic Battles.” No, it doesn’t make sense.
GC - Galactic Conquest. It conquests the galaxy. You can tell it apart from the other GC because this one is in “Galactic Battles” and that one is in “events.” No, it doesn’t make sense.
GG - General Grievous. Another for my collection.
GI - Grand Inquisitor. Also the place where the gas lives.
GK - General Kenobi. Hello there!
GL Rey - Rey. The nickname is longer because just saying "rey" could be like three different characters and CG really screwed the pooch on this GL's name.
GMY - Grand Master Yoda. He's a support character, which makes no goddamn sense.
Hobo Ben - Ben Solo. It's because his sweater has a hole in it and a stain on it. So he looks homeless. CG really tried to make Swolo a thing, but it turned out Hobo ben kinda sucks.
Hoda or Hyoda - Hermit Yoda. Judge him by his size, do you?
HRS - Hoth Rebel Scout. Because the Hoth Rebel Soldier sucks and you'll never use him.
HRS - Hoth Rebel Soldier. I'm just kidding. It's still Hoth Rebel Scout. The soldier sucks balls.
Idaho Vertato - Iden Versio. Someone in my guild's spellcheck changed her name, and goddamn if it isn't the funniest thing I've ever seen, so I'm making it a thing.
Inks - Inquisitorus. A necessary evil.
IPD - Imperial Probe Droid. It must have self-destructed.
ISC - Imperial Super Commando. I have no idea why this guy gets his own acronym. He's garbo.
JKA - Jedi Knight Anakin. He is on the council, but was not granted the rank of master.
JKCK - Jedi Knight Cal Kestis. But I think “JCVD” every time.
JKL - Jedi Knight Luke. Like his father before him.
JKR - Jedi Knight Revan. One was silver and one was orange. Hashtag NotMyRevan.
JMK - Jedi Master Kenobi. He has the high ground.
JML or Grumpy Luke - Jedi Master Luke. Unlike his father.
JTR or RJT - Rey (Jedi Training). Seriously they could have just named her "Rey (Galactic Legend)" and at least the naming convention for Reys would have been consistent.
JW Cheese aka Jedi+Wat - The team consisting of JKL / JML / Wat, and any other two characters. Commonly referenced in my conquest guides and probably the only reason anyone ever visits this page.
KAM - Ki-Adi-Mundi. He comes from France.
KK - Kyle Katarn. Just a guy with a lightsaber.
KRU - Kylo Ren (Unmasked). Shouldn't it be "unhelmeted?"
LS - Light Side (usually with a number and letter, such as LS2A, which would be Light Side sector 2, node A)
LV - Lord Vader. Noooooooooooooo!
Mando - The Mandalorian. ...or he can bring you in cold.
MJ - Mara Jade, The Emperor's Hand. Everything we hoped she'd be.
MM or Mom or Mothra - Mon Mothma. Several Botan Rice Candies died to acquire these plans.
OG Kylo - Orignal Gangster Kylo aka Kylo Ren. Whatever. You're not gonna use him anyway.
Old Ben - Obi-Wan Kenobi (Old Ben). Of course you know him. He's him.
PHX - Phoenix Squad. They kinda suck now and are harder to farm. There are better options for a new player now. Don't trust any guide written before March of this year.
QGJ - Qui Gon Jinn. Promise me you'll train him.
RG - Royal Guard. Shouldn't they be "Imperial Guard?"
RH Finn - Resistance Hero Finn. There's something he's got to tell you...
RH Poe - Resistance Hero Poe. That's okay, he can hold.
ROLO - Rebel Officer Leia Organa. She knows.
RT - Rose Tico. People use this abbreviation all the time. Trust me.
SAss - Sith Assassin. Sassy!
Scav Rey - Rey (Scavenger). See why that GL name was dumb?
SEE - Sith Eternal Emperor. Somehow, he returned.
SET - Sith Empire Trooper. One of the few decent pretaunt tanks in the game.
Shore - Shoretrooper. You’d think this guy would be ST, but there’s already an ST. Or two. Or like seven. Good thing it's totally unambiguous which character we mean when we say ST, as this index will clearly demonstrate.
SK - Starkiller. Bring the sky.
SLKR - Supreme Leader Kylo Ren. The starter GL for the masses.
Snow - Snowtrooper. Don't be fooled. People will tell you this means "Jon Snow," but they're lying.
SRP - Scarif Rebel Pathfinder. I'm pretty sure the paths on Scarif were all clearly marked though.
ST - Sith Trooper. Don't be fooled. People will tell you this means "Stormtrooper," but they're lying.
ST - Stormtrooper. Don't be fooled. People will tell you this means "Sith Trooper," but they're lying.
ST Han - Stormtrooper Han. Don't be fooled. People will tell you this means "Sith Trooper Han," but they're lying.
TFP - TIE Fighter Pilot. My favorite action figure when I was a kid. They just look so cool!
UR - URoRRuR'R'R. Did they seriously name him after the noise he made that one time in the movie, like he's some kind of Pokemon?
Best guide to SWGOH acronyms. FO part gets me every time.
