The phrase ay como llueve simply means oh how it rains in Spanish, and the clip has circulated as a short reusable reaction audio on soundboards and in meme edits rather than as a song or film quote. Its humour comes from treating common rain as a major event, so creators reuse it whenever a scene needs instant, recognisable complaining about the weather. Because the words are easy to understand even for non Spanish speakers from context, the sound keeps travelling across short videos, group chats and rainy day compilations.
