fish or cut bait

你也许猜得到: 动词fish意思是钓鱼。Bait是系在钓鱼线上的鱼饵。所以这个习惯用语如果直译就是要么钓鱼，要么干脆切断鱼饵。Fish or cut bait最初出现在十九世纪。一名议员在国会就一项议案进行表决前对与会者说了这句话，敦促大家当机立断，作出是或否的明确表态。

used to tell someone to take action or to stop saying that they will

要么全力以赴，要么索性放弃;下定决心就别再动摇

He's been promising voters that he'll support gun control, now it's time to fish or cut bait.

他一直向选民许诺他会支持枪支管制，现在是下定决心的时候了。

Either go on to college or go out and find yourself a job. It's time to fish or cut bait!

你要么就去上大学，要么就出去给自己找份工作，是做出决定的时候了，别再犹豫不决。
