same here.
it hasnt been a year since i started watching jdramas, but i already know enough to start and end a conversation in japanese. XD
i can understand more than i can speak though. XD

I've been learning japanese for quite a long time, and I lived in Japan for five years.....
I can speak Japanese already, and I communicated with the Japanese people
Japanese is not that easy as you think
For example, I have ate is different than i'm eating
I really can't explain properly but you shouldn't only know the words but the tenses and others....
I suppose you all kow Hiragana, Katakana and Kanji words too...^^

konoyarou-you bastard

kuso ama-you bitch

bakero-fuck you

bakayaro - fuck u asshole

Baka - idiot

ecchi - sex

henjin - weirdo

teme - damn you

bakatare - damn idiot

aho - stupid

baba - old hag

jiji - old fag

baka!

i hear it all times!! in dramas!! nyahaha!

I remember a few. Kokoro - Heart. I'm not quite sure how to spell either Revolution or Miracle, though.

baka & nani - fav word..
