Borderlands 2 is a 2012 looter-shooter by Gearbox Software, and Angel is its mysterious ECHO guide, the daughter of Handsome Jack who speaks to the Vault Hunters through screens and audio logs. Short ECHO voice lines like this one circulate as reaction sounds because they are clean, instantly recognizable game dialogue. Like other clipped callouts such as Enemy Spotted, it gets reused in edits and memes for moments of confusion, and like terse reaction sounds like nope it works as a deadpan punchline without needing context from the campaign.
