GLaDOS was introduced in Valve's Portal in 2007 and returned in Portal 2 in 2011, voiced by Ellen McLain with a processed, emotionless delivery. As the game's testing AI, she spends the story mocking the player with polite, cruel logic, which made many of her lines easy to lift as standalone reactions. This insult spread through gaming clips, streams and soundboards because it needs no setup to understand. It remains popular as a compact roast that fits gaming fails, bad takes and any moment where a choice looks indefensible.
