YOLO is an acronym popularized by the rapper Drake in 2012, meaning “you only live once”, used to express the view that one should make the most of the present moment without worrying about the future.

The term is a meme among stock traders on Reddit, who use it when making irresponsible bets that sometimes pay off anyway. More broadly, it has come to characterize the attitude that has captured a certain type of bored office worker in recent years.
