Meaning

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.
