.Does anyone have a literal translation of the term 'osu'? Sometimes people spell it 'oss' or 'ous'. This question is not restricted to JuJutsu but Japanese arts in general. Hell, I've heard it often enough from non-Japanese arts. But if you do answer this I'd be interested to know what art it comes from to see if there is a difference in usage. I have noticed some people using it more than others and the context behind it sometimes seems to lead towards a few slightly different meanings. But I haven't been able to find any sort of literal translation or use. The closest I have found is that it is a shortening of the term 'onegaishimasu' as a result of a bit of laziness and over-familiarity. But it's use doesn't seem to always follow that description. Does anyone know?
