Lineage 2 is NCSoft's classic Korean MMORPG, released in 2003, where support classes like the Blade Dancer cast dance buffs that strengthen the whole party. The short casting chime became familiar to players through years of grinding, sieges and raid videos, and later spread onto soundboards and meme edits as a shorthand for powering up. Like the Fortnite default dance meme, it signals a celebratory move, while its game-sound roots put it beside clips such as the bomb has been planted callout and the enemy spotted callout.
