I used to be a JK.
When I was watching TV a few days ago, I heard some unfamilier words from it.
Such as JC, JK, Oke-ru...
Are they Japanese or English? Or some different languages?
Can you guess what they mean?
JK is not John F. Kennedy:P
JC is not Jesus Christ.
JK is Joshi-Kousei!!
Joshi=Girls
Kousei=high school students
Well, then JC means Joshi-Chugakusei.
Chugakusei=Junior high school students
They say, fake school uniforms are very popular among JK(should I put "s" for it?) now.
In Tokyo, there is a school uniform shop called Conomi
and you can find your favorite style.

Of course, they have their own school uniforms but after school.
they change clothes to fake one or just arrange it to their "original" style.
If you see JK wearing uniforms around Shibuya, it might be a fake one.
