The name Daniel san is widely associated with The Karate Kid, where Mr Miyagi addresses his student Daniel LaRusso that way, giving the line an instantly recognisable teacher and student dynamic. The Spanish words hay que hablar simply mean we need to talk, which turns the reference into a clear call for a serious conversation. Short dubbed and reposted clips like this circulate easily in chats and edits because the wording is understood even out of context, and the respectful san adds a familiar, slightly formal tone that makes the summons sound funnier and more dramatic.
