Why does crayon Shinchan often say "Osama"?

I'm speechless about the madman on the second floor who wants to share a room. . . . .

To tell you first, I can speak Japanese (* _ _ *) hee hee. ...

If you mean "Osama", then I will tell you O(∩_∩)O, this is the 2006 theatrical version of Dance! Friend's reason! (I suggest you have a look! )

But if you say "Obasan" (ぉばさん), in Japanese, Obasan is pronounced directly in Japanese, meaning: sister-in-law, aunt. Generally refers to middle-aged and elderly women. By the time I arrived in Hong Kong and Taiwan, the word had actually gone stale, and it had been extended to: type 38 old woman. Because the Chinese dubbing of Crayon Shinchan is provided by RTHK, which is the explanation of the last sentence!

I hope it helps you! ^_^
