The oof was Roblox's default character death sound for over a decade, playing every time a player's avatar was eliminated. The short grunt was created by video game composer Tommy Tallarico for his 2000 game Messiah, and a licensing dispute over its use in Roblox ended with the sound being removed from the platform in 2022 and replaced by a new death effect. Long before that, the oof had already escaped the game, becoming one of the internet's most quoted gaming sounds and a staple of fail compilations alongside reaction clips like Bruh.
