I'm on the first season of Durarara!! (Coalgirls Subs), and on the Message Board Saika often posts random words like Love, Peace, Cut, etc. - All of which are subbed except for this repeated character.
Initially I thought that Saika might be spamming with DESU DESU
or something similar (I don't know why I thought that), but googling this didn't return any results.
So my question is, What is this word, Saika is constantly spamming the board with?
Mother
seems to be the correct translation.
