League of Legends is a long-running team-based multiplayer game from Riot Games in which players communicate quickly through pings instead of typing, and the retreat ping became one of its most recognisable warnings. In matches it tells teammates to pull back before a fight turns dangerous, a use that carried naturally into streams, highlight reels and short-form edits. Like a danger alarm, it now works outside the game as shorthand for backing off, changing plans or admitting defeat before things get worse.
