Noun, A small and most often a white ball of toilet paper, tissue paper or material fuzz tangled on one or more ass hairs or pubic hairs. Although a dingleberry is more common on men it is not uncommon on Italian or Middle Eastern women too wear during mating season. A Dingleberry, when ripe, is often brown but maybe red depending on dingleberry's anatomical location.
A dingleberry is the marriage of poo and toilet paper. That eventually entangle itself all up in your ass-pubes. Like a cacoon of particles that should have gone down with the rest.
You really don't know you are sporting a choice dingleberry unless, you are all up in your ass scratching, and damn near scream when you rip that nasty nest from your crack. It'll wake you up, and hopefullyencourage a good shower to follow!
