In Bleach, created by Tite Kubo, the Garganta is the void portal Arrancar use to move between Hueco Mundo, the World of the Living and Soul Society, most memorably the Espada, Aizen's ten strongest Arrancar. The anime gave that opening a signature tearing noise, and clips of it spread through anime forums, AMVs and soundboards as a reusable teleport sound for villain entrances. Fans still use it because it is tied to a specific threat level, not just any character arriving, which makes the reference instantly readable to other Bleach viewers.
