Shared mainly as a short WhatsApp audio, this clip belongs to the wave of random voice notes that Spanish speaking users forward as ready made reactions. Its humour comes from mixing arigato, the Japanese word for thank you, with the vague Spanish tag cosas y más, which makes the gratitude sound both sincere and absurdly broad. No single film, show or creator is tied to the recording, and it spread simply because it is short, quotable and easy to drop into everyday chats, stories and short meme edits.
