Is the “YOLO” craze officially over? Saturday Night Live's Lonely Island made a music video about the hip catchphrase—which means “you only live once”—featuring singers Adam Levine and Kendrick Lamar. The song flips the script on how most of us risk takers YOLO, instead asking viewers to think carefully before doing anything. Go to clubs? YOLO, so don’t hurt your ears. Do drugs? YOLO, so don’t go to jail. Is it funny? That’s up to you. You’ll be humming it later.
