Old Fart （くそったれ じじ）

He Says:
kusottare jijii　（くそったれ　じじ）=you shitting old goat!
jijii means old guy like more than 70years old. and kusottare is fucking shit(see the one Dec.14 blog). So you can say this word to old men, but can say to young men. That'll be more powerful insult.
And that'll be so nice if a female uses the word to men.
You can say it to your fucking shit boss or someone.
I bet many japanese don't expect you non-jp people can use this word,
so they would be so surprised when you say this word.
jijii is old man,and old lady is babaa.
So kusottare babaa is also cool to say to them!

She Says:
Mmmmm....I don't have anything to add about this one.
