Usuratonkachi means thin hammer so basically it means Useless

I'm pretty sure it means something along the lines of 'freaking idiot' in Japanese.

Used in episode 101 of Naruto

Japanese, literally translated to "thin hammer". can be taken as being called useless. But in the context of the Naruto universe, it takes on a sexual meaning. so, not useless. but an insult to ones penis
