The horn is associated with Blade and Soul, the martial arts fantasy MMORPG often shortened to B&S, where horns and drums mark combat and large-scale encounters. Clips of its battle signals were ripped and shared on soundboards because the sound works outside the game too, detached from any specific scene. Its long, echoing blast became a shorthand online for war starting, an army moving, or a player committing to a fight, and it remains popular for gaming edits that need instant epic scale without music.
