The sound comes from Tom Clancy's Rainbow Six Siege, Ubisoft's tactical shooter released in 2015, where attackers must plant a defuser at a bomb site while defenders try to stop them. Because planting leaves the operator exposed for several seconds, the audio has become shorthand for high-stakes moments in gameplay videos. Clips of plants, clutches and failed defuses circulate on YouTube, Twitch and TikTok, and editors reuse the sound to signal that a round is about to be decided.
