In a rainy-day edit, use it right after the first shot of rain, then follow it with a short shocked reaction sound and a light laugh to close the joke, before any longer commentary takes over the scene.
About this sound
This four-second clip is a short Spanish meme sound built around the spoken phrase about rain, delivered quickly and plainly in just a few words. It feels light and silly, like a quick joke shared on a rainy afternoon, and lands best as a sudden, playful reaction rather than a serious weather comment.
