Random death match, this basically means you've killed someone for no apparent reason; an example of this: I see a hobo sitting in the street minding his business, I kill him for no reason at all, this would be 'rdm'. More complex aspect of this would be if I said the road outside my base is KOS and I kill anyone who walks upon it, this would be RDM as well. In simple terms killing someone for a non-rp reason.
