Hm. I'da thought that the Jiu-Jitsu thread title and non-aikido content would have landed it in the brand spankin' new "Non-Aikido Martial Traditions" forum for sure! Though "Humor" definitely sounds like the more reasonable forum for it. Go figure. [shrug]
Oh yes, if it were in the humor section I could translate Jiu-Jitsu with Jim breen's WWWJDIC service:
Jiu: 慈雨; 滋雨 【じう】 (n) welcome (beneficial) rain
Jitsu: 実 【じつ】... kindness
So Jiu-Jitsu would be the kindness of a welcome rain.
Unfortunately this is not the humor section. So please forget that silly nonsense. Jiu-Jitsu ist just an old transcription of something, which would be written in official romaji as Ju-Jutsu.
