While watching [Cowboy Bebop](https://anjsub.com/watch-cowboy-
bebop/?v=episode13) I came across aa short dialog between the woman bounty
hunter and the little girl:

21:12みんなでどこ行ってきたの？

21:15いい所よ

21:16エドだけ知らんちん

It is the last part in which the girl says エドだけ知らんちん that ちん draws my
attention. Why does she use it? Is it an emphasiser?

How is ちん working in 知らんちん
I guess it's a variant of わからんちん, which is a rare, funny, a little childish
way to say わからん ("I dunno" or "It's all Greek to me"). This ちん has no
important meaning, but one may think it's a kind of
[dimunitive](https://en.wikipedia.org/wiki/Diminutive). わからんちん seems to be
common in some areas, but no one used it in the area where I was born. I
probably heard わからんちん for the first time at the [opening of an anime called
一休さん](https://www.youtube.com/watch?v=KxDR0lT2pLk&feature=youtu.be&t=62).

(ちん is also a rare dialectal suffix used in a part of Kyushu, but I'm not sure
if it's related to this.)
