A man in the pub has tried to express a thought he had about football which actually turns out to be a complete non-idea, utterly meaningless and totally empty of content.
The supposed idea, which seemed really important to him at the time, turned out to be difficult to express clearly. In fact this was because it did not actually make any logical sense or even actually exist as a concept.
It seemed to consist partly of the idea that one team was better than the other. But there was apparently a further twist which included the fact that this was now news to someone, without saying who. This was then elaborated with a long list of players and their abilities, constantly referring to their cost and goal history, returning occasionally to the main theme that one team is better.
Struggling to get across what he was thinking, the 'idea' was expressed with hand movements and comments on the superiority or lack thereof of one team or other, due, he emphasised, to the qualities of the various players.
Fourteen minutes into the monologue, after repeating himself more than fifty times, he finally concluded with an outburst of football word salad. His fellow drinkers nodded sagely and showed visible signs of relief as they changed the subject to immigration.
