How it's used
This term is a harsh, direct insult used to label someone as lacking common sense or intelligence. It carries a stronger, more aggressive tone than simply calling someone 蠢. It is frequently used in moments of extreme frustration when someone fails to grasp an obvious point or makes a reckless mistake.
Examples
He always makes such brainless decisions, it's so infuriating.
Are you brainless? You don't even know how to do something this simple.
