The sound comes from Roblox, the online game platform where a short oof played whenever a player's avatar died. Over time players recorded, remixed and misspelled it as off, and the clip spread far beyond the game into meme edits, TikTok videos and soundboards. Roblox replaced the classic death sound in 2022 after a licensing dispute, which made the original uuhhh version even more nostalgic. It remains popular because almost anyone who played the game as a child recognises it in less than a second.
