Heres the short versions of things such as DM,PG and ect...

Okey so geres the short version of all the meanings. Make sure you learn them and dont just copy them when youre filling any kind of application.

DM-Deathmach~Its killing or injuring other players for no or no good reason.
RK-Revenge Killing~Its killing the player who killed you after you die or even comming back to the place that you were killed right after you get out of hospital.
MG-Metagaming~It's using OOC knowledge in IC chat. Talking about the server and real life in IC chat or using people's name when you dont know them IC.
PG-Power Gaming~Giving your character unrealistic powers. Also forcing other players to RP. Like using /knockout command without /me attempts to knock the man down and then /do succeeds? After the player did /do Succeeds you can then use /knockout command. But the player can also answer /do fails, but must have a good reason of why did you fail. Otherwise hes powergaming.
OOC-Out Of Character~Its talking about real life, out of your roleplay character.
IC-In Character-Its roleplaying your character. Talking in game, acting like in real life.
RP-RolePlay~Playing your role. Almost same as IC. Acting like you would in real life.
CK-Character Kill~It's when your character gets killed and you are no longer alowed to use Your account and you have to create another one. You loose everything, your stats, cars, money, houses and friends. (in IC ofcourse you dont have to pretend you dont know anybody in OOC ) Althought You need an admin and the player agreement to kill someone else's character.
PK-Player Kill~It's killing a player. If you get PK'ed you loose all your memory and friends IC. But you keep your stats and your money,cars and everything. The PK is mostly performed when you are Leaving a street gang or a family or betrading one, Or if you get caught in a dark place and robbed then killed... But you also need an admin to aproove it. Otherwise its not a valid PK...
KOS-Killing On Sight~Killing/DMing everyone on your sight/everyone you see around.
Rushtazing~It's when youre a PD officer on an FBI agent and you run up to the suspect and taze him without reloading your tazer and if the suspect is shooting at you.

My advice is to read the Roleplay guides if youre new at RolePlaying but if you only forgot the short meanings but you know that which is legal and which is not then you can always look up to these. Have fun RolePlaying.
