Mass RDM 

Mass RDM, or MRDM, an abbreviation of “Mass Random Death Match”, is the act of engaging several players in Player vs Player combat randomly, either for an invalid by rules reason or entirely unprovoked. Mass RDM’s usually consist of players on roleplaying games, such as Gmod DarkRP and FiveM shooting a crowd of players unprovoked. Usual excuses for such acts include “I was roleplaying as a terrorist” or another very generic reason to try not getting banned.

Mass RDM is typically a rule on Role playing games and servers, however also exists in garrys mod gamemodes like trouble in terrorist town. In the context of Roleplay servers, Mass RDM is probably the most broken rule.

RDMS 

Rank Don't Mean Shit, Army slang opposite of RHIP Rank Has Its Privileges.

A new Army Second Leiutenant and I, an enlisted AF Sgt., both asked for the same Magazine on a chartered military flight going overseas. The flight attendant handed the Officer the only copy she had and apologized to me as she handed me a similar news magazine. The Officer looked at me and said RHIP. I replied, RDMS, he asked my friend sitting between us what it meant. He didn't say another word on the flight. He knew he was wrong to start something with an enlisted person especially cross-services.
