hehe.. just found website about indonesian slang

Once a week I teach Indonesian in Funabashi international language school.. the payment is not much, but this is for my experience and I can also learn Japanese through teaching Indonesian, coz I have to explain it in Japanese ^^;
I've been teaching for 2 months now, and searching articles in Indonesian, or explanation about Indonesian grammar in google is my habit since then. I found this website just now.. urmmm...
