League of Legends is Riot Games' multiplayer online battle arena game, first released in 2009, and its short voice lines and announcer phrases have become a steady source of meme audio online. Clips like Vai Time spread through gameplay videos, streams and soundboards, where players lift a two-second line out of a match and reuse it as a standalone joke. Its appeal is timing rather than context, so even viewers who do not play recognise the confident call as a signal that action is starting.
