Failsafe was introduced in Destiny 2 in 2017 as the AI of the crashed Exodus Black colony ship on Nessus, voiced with a split personality that flips between relentlessly cheerful and bluntly depressed after centuries alone and the loss of her crew. Players heard her constantly during Nessus missions and strikes, so her lines became shorthand in the community. This hurt feelings line spread beyond gameplay into edits and streams, where Destiny fans and other creators use it as a compact, instantly recognisable reaction to teasing, rejection and minor embarrassment.
