Expanding on above definition, also used in singular sense to describe a person who is simply a moron. The extra suffix is just used to rolling effect and may sound more refined than simply "moron". Expanding on above definition, could also be the merging of moron and marathon to denote the idea of a very large group of idiots running in a race which ended a week ago and thinking that the streets are deserted because they are just way ahead of the pack.
In a heated argument, your say he's a moron, he says you're a moronathon, and you hang your head in defeat.
