Rampage comes from Unreal Tournament, the fast-paced first-person shooter series from Epic Games that began in 1999 and became famous for its dramatic in-game announcer. The voice lines reward players for sustained killing sprees, and Rampage marks a particularly strong run, which is why it stood out in early frag videos and LAN-era gameplay clips. As those clips moved to video platforms and meme edits, the single-word call became shorthand for unstoppable momentum. It remains popular because it is instantly recognisable to shooter fans and adds instant hype to any streak.
