This sound refers to C4 from Rust, Facepunch Studios' multiplayer survival game, where timed explosives are central to raiding player-built bases. Raid clips and base defense montages helped this audio spread through gaming edits, especially in short videos that turn a breach into a punchline or dramatic reveal. It remains popular because Rust players immediately recognize the raid setup and explosion payoff, while non-players still read it as a clear signal that something expensive, chaotic or overpowered is about to happen.
