The line comes from the Brazilian Portuguese version of Finding Nemo, Pixar's 2003 underwater adventure, where a group of sharks trying to give up eating fish celebrate a meeting that ends without anyone becoming dinner. The joke works because the diet twist turns predators into reluctant friends, and the catchy repetition made it easy to lift as a short audio clip. Shared widely in Portuguese-language meme edits and reaction videos, it survives as a quick shorthand for relief after a close call.
