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.
