- 1想都不用想的事；顯而易見的決定（不是罵人沒大腦）
A no-brainer is a choice so easy that you hardly need to think. People say it when they want to stress that the answer is obvious: taking the paid job over the unpaid one was a no-brainer. It is informal, common in speech and in light news, and a little American in flavour, though lots of English speakers use it now. You would not put it in a very serious essay. Though actually, it does not mean the person has “no brain” — it means the problem does not need much brain. The -er makes a noun for the thing itself, the easy decision.
