The Creeper is a hostile mob from Minecraft, the sandbox game developed by Mojang and first released in 2011. Designed to sneak up silently, it ignites with a distinctive hiss before exploding and damaging players and terrain. That two-part sound became one of the game's most recognisable audio cues and spread far beyond gameplay into YouTube edits, livestreams and meme compilations. Creators now use it as shorthand for an ambush, a costly mistake or an ending no one saw coming.
