The name comes from Spanish, where risa means laughter and ardillita means little squirrel, a description of the clip's squeaky, animal like tone rather than a known character or show. No confirmed original source, performer or release year is documented for this version, so it is best understood as a soundboard reaction that spread through shares, reposts and short video edits. Its tiny length and unmistakable pitch made it easy to reuse as a Spanish language laugh reaction, and it continues to appear in chats and meme compilations.
