This sound comes from Finding Nemo, Pixar's 2003 animated film about a clownfish searching the ocean for his son. The mine-chanting seagulls appear when the pelican Nigel tries to help Marlin and Dory, and the birds obsess over every scrap in sight. The scene became one of the movie's most quoted gags, and the chant spread through YouTube edits, meme compilations and soundboards as shorthand for greedy bickering. In Brazil the Portuguese dub turned meu into a mel-like chant, which is why many listeners search for it as mel mel mel.
