Hi John,
I was just discussing this with my wife, who is native Japanese. Apart from the fact that these type of things (people giving themselves titles, especially incorrect titles) drives her to despair

We'd both come to the same conclusion on chichi, although it is also a slang word for nipple, hence my first post on him i.e. he's a "t!t". I also came to the conclusion that he was using Oushi as a name rather than a title, perhaps due to his size he is referring to himself as "bull", hence the title father bull. I don't really know, I don't really care, although I did uncharacteristically waste some time digging into it

. The only consolation was the laughter it gave me
