Phrases like "what the doing" will eventually exhaust their novelty. Internet language burns through its vocabulary quickly, discarding catchphrases the moment they feel predictable. Yet the underlying pattern driving the joke remains permanent.
Whenever content feeds grow overly polished or predictably structured, users push back with deliberate nonsense. Fractured syntax strips communication down to its rawest, most playful components. It turns chaotic video feeds into a shared playground where nobody needs to make complete sense to be understood. The joke is not about grammar. The joke is about collectively acknowledging that the internet has stopped making sense, and deciding that three broken words are all the response it deserves.
