The sound comes from Minecraft, the sandbox game developed by Mojang and fully released in 2011, where it plays whenever the player character loses health. As Minecraft videos exploded on YouTube in the early 2010s, the grunt became inseparable from fall damage, lava slips and surprise mob attacks in viewers minds. Clips and edits later lifted it out of the game entirely, using it as a universal shorthand for getting hurt. Its familiarity across generations of players keeps it popular in memes, streams and short-form edits today.
