The sound comes from Lego Indiana Jones: The Original Adventures, released in 2008 by Traveller's Tales. It reuses the death system from the earlier Lego Star Wars games, where heroes do not bleed or scream but simply fall apart into bricks and drop studs. Players heard it constantly through co-op play, so it became shorthand for a harmless, child-friendly game over. Clips later spread to YouTube and soundboards, and like the roblox oof, it is now used far beyond the original game as a quick death joke.
