Anal intercourse with an anus lacking cleanliness and a pleasing appearance. Hair, lint, and dingle berries are usually present as well as an offensive odor. Upon retraction from the anus one will usually find trace amounts of Peat Moss on their penis.
Man, last night I was feeding it to The Fat Smelly Girl. I was balls deep, Moss Boggin for hours....It was Filthy.
