The phrase comes from Jamaican patois, where pon is a common form of upon, giving the line its distinctive rhythm and directness. Shared as a short voice clip on soundboards and in chats, it spread because the refusal is instantly understandable even to listeners unfamiliar with the dialect. Its longer ten second delivery sets it apart from one word reactions, letting the speaker's frustration build before the final line lands. That pacing has kept it in use as a humorous but firm response to pressure, nagging and unwanted requests online.
