YOLO, short for 'you only live once', was popularized by Drake's 2011 single 'The Motto' and quickly became defining slang of the early 2010s. The phrase turned into a meme shouted before reckless stunts, dares and pranks, peaking alongside Vine and early YouTube fail compilations. Saying 'go yolo' before jumping, flipping or attempting something ill-advised became a recognizable comedy setup online. The joke endures because the acronym still reads as instant permission to act recklessly, making the shout a timeless cue for chaotic clips.
