grundelberry 

The wicked stepsister of the dingleberry. Formed when one has diarreah or other digestive ailment, the grundelberry is a vulgar clump of human excrement that forms in small balls around hairs found in the human grundle.

Ex. When one goes to Taco Bell and eats three 1/2 lb Beef Combo Burritos, one will experiance gastro-intestinal defiance leading to grundelberry infestation of the grundel.

Grundleweed

A tumbling mass of pubic hair that accumulates in a heavily used and rarely cleaned bathroom. The grundleweed may then journey to other areas of the house by catching drafts of air and rolling along the ground.

My girlfriend and I were about to get it on when a massive grundleweed rolled into the room and ruined the moment.
