>>939200The fatcat poster becomes tired. They start posting the fatcat later and later in the threads because they struggle to think of two words that at least vaguely resemble "fat cat." Eventually they'll miss a thread, maybe two which grows and grows until they can no longer consistently post the fat cat. Then another poster who liked the fat cat ritual will notice the drop off, step in and post fat cat until they too run through all the synonyms the previous poster did. The cycle will continue ad infinitum.
Or they could just try using different languages like the other anon suggested.
