crunch time經常用在比賽中，假如比賽只剩5分鐘了，兩個球隊比分相差無幾，這時，就可以稱作crunch time，中文可以翻譯為關鍵時刻。

例句：
It is crunch time for Lakers, one more score will secure the victory.
對于湖人隊來說是個關鍵時刻，再拿一分就能確保勝利。

請看下面的話：

The Wizards won! It was a great game. You should have seen it. Rogers hit seven threes, and the Wizard were down by ten at the half, but then they came back in the third quarter, and the Bulls collapsed during crunch time.

現在，crunch time還有其他的解釋和用法，假如公司在做一個項目，要求下周必須做完，所剩時間不多了，必須抓緊時間在最后期限前做完，那么也可以用crunch time，可以翻譯為最后的時間，最后的期限。

例句：
"We've got three weeks left to complete six weeks worth of work. Looks like we'll be living on take-out for a while."

"I freakin' hate crunch time."
