盲めくら打うち

noun

blind punching; random firing; haphazard attack

Metaphorical use: acting without aim or plan, like a blind person striking out. Often used in contexts of shooting, fighting, or making unguided attempts. The term めくら is now considered sensitive when referring to people, but this compound is still used idiomatically.

• 暗くら闇やみの中なかで盲めくら打うちをしても当あたらない。

  Even if you punch blindly in the dark, you won't hit anything.

• 彼かれは計けい画かくもなく盲めくら打うちのように仕し事ごとを始はじめた。

  He started the work haphazardly, like random firing, without a plan.
