A smallish, semi-dry, extraordinarily tenacious remnant of fecal matter which, when unwittingly rolled into a mixture with toilet paper lint by the action of wiping, becomes almost irremovably entangled among ones anal hair, a situationality exacerbated by the vigorous chafing and friction between the buttocks and most commonly remedied by the sad and almost entirely unavoidable remedy of plucking out at its root the individual hair to which each dingleberry is conjoined. Of related interest, dingleberries are often noted as having the vague odor of undigested corn or peanuts.
Then, dingleberry is uphelp by a coarse and curly hair between the fingers about 6 inches in front of the face and marveled at by the viewer, who experiences waves of anger, wonder, and bitterness while contemplating in earnest the sordid and very stupid affair of shaving the unfortunate crease in his or her own ass.
A tiny dried up or petrified ball of feces that gets caught in a man's ass hair. It can be the result of not washing your ass or not properly wiping your ass after taking a crap.
When the hippie/stoner pulled down his pants, the girl caught a glimpse of his dinkleberries and refused to have sex with him.
