意味

Brain-dead play — doing something on complete autopilot without thinking, used for mindless grinding or careless mistakes.

Literally 'brain death,' 脳死 in gaming describes performing an activity so mechanically that it requires zero thought. It can be positive (脳死で周回できる — you can grind it without thinking) when describing easy, mindless tasks, or negative (脳死プレイ — playing without using your brain) when criticising careless play. The medical origin makes it somewhat controversial.
