What is that Japanese nickname-insult Sasuke always calls Naruto?

(previous answer) Bakka?

[I think it's "Usuratonkachi". Isn't that the one you're looking for? :D]

Umm, no. that isn't what Naruto means. Naruto is actually a ramen topping, and it translates roughly into English to be "Fishpaste".

I'm not sure if this helps but sasuke calls naruto dobe which means idiot or deadlast, and naruto calls sasuke teme which petty much means bastard! yay. anyway hope that was usefull! pease out, yo!

Usuratonkachi - Sasuke's insult is something more along the lines of "you good-for-nothing .." since usuratonkachi means thin/usura, hammer/tonkachi - a thin hammer is obviously no good for anything you would need a hammer for.

A clearer alternative to dobe is probably "dunce-bat" .. I think ..

i think dobe translates into 'dead-last' which Sasuke calls Naruto becasue he was always the last in their class at the academy.
