League of Legends is a team-based multiplayer online battle arena game in which players use pings to communicate quickly without voice chat, and the enemy missing ping tells teammates that an opponent has left their lane. The short alert became familiar to millions of players through regular matches, streams and gameplay videos, where it often signals danger before a surprise attack. Like an enemy spotted warning, it works because it is instantly understood even by people who have never played the game, which keeps it useful in edits, reactions and gaming memes.
