This clip is mainly known online as a short "oi" sound effect used in YouTube edits and meme videos. Based on the available information, it is circulated more as a standalone reaction sound than as a clearly credited quote from a specific film, show or game. Its popularity comes from how quickly it signals attention, disapproval or surprise in less than a second. That makes it easy to drop into reaction-heavy edits alongside familiar cues like a shocked sound without slowing down the pacing.
