The line comes from Overwatch, Blizzard's team shooter released in 2016, where Reaper is a masked mercenary and former Blackwatch commander voiced with a harsh, whispering growl. Players could hear the quip as an in game voice line and soon began exporting it beyond matches. Shared on soundboards and in short edits, it became a standalone reaction for anyone denying suspicious behaviour while sounding entirely guilty. Its popularity endures because the delivery is instantly recognisable, short enough to replay, and flexible enough for gaming clips, villain memes and ironic self defence online.
