The clip circulates as part of a numbered series of Portuguese swear word recordings, with this entry marked as number five. According to the original uploader notes, it was recorded from a YouTube video by Kesyn and Skelter and shared among other funny Portuguese clips. Ruca is the Portuguese name for Caillou, which adds to the humour because a children's cartoon voice is linked to strong adult profanity. That contrast helped the sound spread as a reaction audio in edits, chats and soundboards across Portuguese speaking communities online.
