中國古代有句名言：“花開堪折直須折。”意思是教人莫負好時光，也有人理解為及時行樂。國外也有一群人把及時行樂奉為信條，他們就是YOLO一族。YOLO是英文單詞的首字母縮寫，意思是“你只活一次”。

YOLO is an acronym for "you only live once". Similar to carpe diem or memento mori, it implies that one should enjoy life, even if that entails taking risks.

YOLO是“你只活一次”的英文首字母縮寫。和拉丁語的“及時行樂”或“死亡警告”相類似，YOLO的寓意是人應該享受人生，即使需要承擔風險。

It has become a popular Twitter hashtag. Some youth have said that it is their motto, and actor Zac Efron has a tattoo with the acronym. The phrase and acronym are used in merchandise worn by teenagers such as hats and t-shirts.

YOLO已經成為一個流行的推特標簽。有些年輕人稱YOLO是自己的座右銘，演員扎克?埃夫隆還刺了一個該縮寫的紋身。這一縮寫詞還被用在青少年穿戴的帽子、T恤等商品上。
