The clip comes from a recording shared by the YouTube channel Kesyn & Skelter, part of a collection of funny Portuguese clips that circulated among Portuguese-speaking viewers. Mãe do Ruca became recognisable through the blunt, everyday phrasing and the exaggerated disgust, which made the short audio easy to reuse outside its original video. It spread mainly as a reaction sound for gross, smelly or absurd situations, similar in spirit to other short disgust reactions such as Eww brother eww. Its lasting appeal is its simplicity: one voice, one complaint, and a reaction that needs no context to understand.
