The underlying oof became widely associated with Roblox because it played when characters died or reset in older versions of the game. The vocal originally appeared in the 2000 action game Messiah and was created by sound designer Joey Kuras. After years of use in gameplay videos and online jokes, Roblox removed and replaced the sound in 2022 following a licensing dispute. Auto-Tuned remixes preserve its recognizable delivery while turning the brief grunt into a more musical reaction for gaming memes and edited fail clips.
