薄鈍(うすのろ)-- an i*iot
Just to note, I'm not sure exactly how insulting this word is, or where it stands on the obscenity scale, but I've seen it translated as "dumb ****" in a fansub. I'm guessing it's not nearly that bad, especially since fansubs can be less than accurate, but I'm not sure. Can anyone clear this up?
