A person or persons who mumble incessantly to spite the
people around them. The
people in question mumble continuously in order to fill a space or situation with as much interference as humanly possible with the aim of getting under the skin of others in their vicinity. These types are often referred to as being from "MUMBOLIA". Also they repeat the same mumble sound often which would be referred to as a "MUMBOLIANISM". These
people are found quite readily in the realms of the HAM radio operator and are the bane of "normal speaking radio stations on the air".
