The line comes from Star Wars: Return of the Jedi, released in 1983, where Admiral Ackbar, commander of the Rebel fleet, realises the attack on the second Death Star has been anticipated by the Empire. His warning became one of the film's most quoted moments and later spread online as a reaction meme, used whenever someone spots a setup, scam or hidden danger. Its short length, clear meaning and instantly recognisable delivery have kept it in regular use in videos, streams and edits decades after the film's release.
