The phrase animes e mangas is Portuguese for anime and manga, so the clip circulates mainly among Brazilian and Portuguese speaking fandom communities online. Rather than coming from a single famous scene, it spread as a generic label sound that creators reuse whenever the topic shifts to Japanese animation or comics. It sits alongside other short fandom cues like anime ahh and tuturu on meme soundboards, where a two second announcement is enough to set context before a list, review or joke without needing an explanation or an on screen caption.
