A Mudge Fuglet is something that has been left around in the rain, mud and desert being eaten alive by rabid bunny rabbits and/or coyotes. Often used as an insult to describe a lazy person, or a turd monkey. This insult is one of the most cruelest profane terms that anyone could use in the english language.

Mr George: Oh I mean, shoot...I have to watch my damn mouth around you Mudge Fuglets.
