This sound comes from League of Legends, where the line is delivered as a short in-game voice line. It began circulating as a standalone clip on soundboards and in gaming edits, where creators used it to introduce tense, spooky or villainous moments rather than as a straightforward game sound. Its appeal comes from the contrast between the calm delivery and the threat it implies, which makes it easy to reuse outside the game. It remains popular in short-form edits, horror-themed clips and reaction memes because the warning sets up a scare or twist without needing any context from the match.
