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".
"Oh God sounds like the Mumbolians are out in force today!"
"CQ CQ any stations outside Mumbolia on this frequency!"
