Widowmaker is the French sniper hero from Blizzard's team-based shooter Overwatch, first released in 2016, and the line is one of her in-game voice lines. As clips from matches, hero showcases and fan edits circulated online, the phrase was picked up by soundboards and short-form creators who used it as a shorthand for sudden focus or suspicion. It has stayed popular because it is short, instantly recognisable to Overwatch players, and flexible enough to fit gaming moments, including an enemy spotted in a match, reaction videos and everyday jokes about noticing something at last.
