Yolo is the abbreviation for: you only live once.

Yolo是You only live once(你只活一次)首字母的缩略词。

“You only live once”的出处最早可追溯到19世纪，出自于法国作家巴尔扎克著作《邦斯舅舅》。YOLO有及时行乐的意思，目前该词已经成为一个非常流行的网络词汇。据外媒报道称，YOLO已被部分年轻人标榜为座右铭，一些好莱坞演员还刺了该缩写的文身。

Similar to carpe diem or memento mori, it implies that one should enjoy life, even if that entails taking risks.

YOLO和“活在当下”或“死亡警告”类似，意思是人们应该享受生活，即使需要承担风险。

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已经成为推特上流行的话题标签。有些年轻人称YOLO是自己的座右铭，演员扎克•埃夫隆还刺了一个该缩写的纹身。这一缩写词还被用在青少年穿戴的帽子和T恤等商品上面。
