Flash has been a core summoner spell in League of Legends since the early years of the game, letting every champion blink a short distance on a long cooldown. Because almost every player takes it, its activation sound became one of the most familiar cues in MOBA culture, heard constantly in ranked games, pro play, streams, and highlight montages. Korean players call it jeommyeol, and clips using the effect spread widely on gaming soundboards where it is reused for instant escapes and surprise repositioning jokes outside the game too.
