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.
