The phrase que os calleis is everyday peninsular Spanish, using the vosotros form aimed at more than one person, which is why it fits group scenes so well. As a soundboard clip it circulates without a single confirmed film, show or creator source, shared mainly for the delivery rather than a known character. Short Spanish reaction audios like this travel quickly through chats and meme edits because the meaning is clear even with basic Spanish. It remains popular for classroom, family and friend group jokes about noise getting out of hand.
