The line comes from the Firebat, a Terran infantry unit in the real-time strategy game StarCraft, first released in 1998. Firebats were known for their short, punchy voice lines, and this one was used when the unit was selected or given attention in-game. As StarCraft clips were ripped and shared on soundboards, the line took on a second life outside matches, becoming a compact way for editors to signal that a character or player has just noticed something. Its brevity and instantly recognisable game origin keep it useful for quick reaction edits.
