The phrase comes from military shooter games, most famously the Tactical Nuke killstreak in Call of Duty, where an incoming strike ends the match. Online, creators stripped the warning and explosion into a standalone meme effect for exaggerated endings. It now sits alongside the vine boom sound in edit culture, used less for realism and more for signalling that something has gone completely over the top. Its short warning-to-blast structure makes it easy to reuse across gaming clips, fails, and reaction videos.
