• Usage
• いい度胸してる
• いい度胸じゃねぇか

Usage

Literally, ii dokyou いい度胸 is a phrase combining the i-adjective ii いい, "good," with the word for "bravery," dokyou 度胸.

If we were being honest, telling someone they have an ii dokyou would mean they're "brave," that they have courage—it would be a compliment.

But often the character saying this stuff isn't being honest—he's a villain, a bad guy, in some position of authority—so ii dokyou is more like commenting on the courage someone has to have to dare defy you. The nerve they must have to challenge you.
