臭くさいもの身み知しらず

expression

people are blind to their own faults

Proverb meaning it is difficult to recognize one's own shortcomings, just as one cannot smell one's own body odor. Often used to point out hypocrisy or lack of self-awareness.

• 彼かれはいつも他た人にんの悪わる口ぐちを言いうけど、臭くさいもの身み知しらずだよね。

  He's always badmouthing others, but he doesn't see his own faults—it's like the proverb says, 'one is blind to one's own smell.'
