rdm

Abbreviation for roadmen. A well known groupchat on twitter. They tend to invade the timeline and create a tradition like Lai Day a day where you drink Lai Tea.

I really want to be part of the rdm groupchat, they seem to be really close and are amazing friends.

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.
