Translation of "Idiotic" in Japanese

"It's been a while since we had a serious conversation, eh." "That's for sure. We usually only have idiotic conversations."

「久しぶりに真面目な話したね」「確かに。普段アホみたいな話しかしないもんね」

Forty percent of the workforce are white-collar workers, most of whom have some of the most tedious and idiotic jobs ever concocted.

労働力の４０パーセントはホワイトカラー労働者であり、その大部分は、退屈でばかばかしいデッチアゲ仕事をしている。
