YOLO

Popularized by the WallStreetBets community, YOLO (You Only Live Once) describes an all-in trade where a trader concentrates their entire portfolio -- or more, using leverage -- into a single high-risk position. The archetypal YOLO trade involves buying short-dated, out-of-the-money options that will either produce life-changing returns or expire completely worthless. Keith Gill's (Roaring Kitty) deep value bet on GameStop is arguably the most famous YOLO trade in history, turning roughly $50,000 into tens of millions.
