The line comes from Warcraft 3, Blizzard's 2002 real time strategy game, where banshees are undead Scourge units built at the Temple of the Damned. It is one of their spawn responses, played when a newly trained unit appears and awaits orders. As Warcraft sounds were ripped and shared on early soundboards and in custom maps, this short response survived outside the game as a standalone reaction. Its mix of fantasy lore and reluctant tone keeps it useful for summoning jokes, undead characters, and dramatic entrances long after release.
