玩你都不用脑子
[wán nĭ dōu bù yòng năo zi]
The nickname '玩你都不用脑子' translates to 'Don't even need to think for you.' It’s often used sarcastically to describe someone who doesn’t seem to require any thought or effort, maybe because the task is too easy or because it’s meant to belittle others in an exaggerated manner. It may imply that whatever the target is doing, it can be done without any thinking which is somewhat insulting.
