The phrase itself is a Spanish expression invoking Poseidon, the sea god from Greek mythology, as a humorous way to swear surprise, similar to saying by Zeus beard in English. As a short audio clip it circulates mainly as a WhatsApp voice message and reaction sound, where its brevity and clear delivery make it easy to forward, reuse in chats and drop into short videos. Its staying power comes less from a single famous scene and more from that everyday usefulness, a ready-made exclamation for moments that feel too absurd for a normal reply.
