Very silly reason.
Heard wow (old NW) from a forum,
Registered the game with my very former nickname (there used to be different game and forum accound names),
Mailed many nations to accept me in,
USSR replied (their very first set with Novii),
it was asking for a state name so next set I wrote Soviet Red State (I was in USSR..),
it was asking for a leader name (wtf??) so I wrote SRS for Soviet Red State..
very lame since I dont use those nicknames anywhere else except for NW
SRS
wow (2003-2007):
USSR - LOTR - NTN - LoR - WLF
nw:
WLF - USSR - SV - ICN - LoR - SKY - CR
Long Live the Nation
Long Live USSR
