When wiping your butt with cheap toilet paper, pieces of cheap toilet paper catch/cling to anus hair(s), therefore having berries that dingle from your butt.
A dingleberry is a peice of shit that doesn't know how to swim so she hangs onto your anal hairs for her life while you are pushing Mr. Brown. Dingleberries plural for dingleberry.
Bits of turd that fear the cold icywaters of the toilet, preferring to cling for dear life onto the hairs between your cheeks. Only found in males. If you find a chick with dingleberries, she's either a tranny or of Greek descent.
Bugger, the TP ran out before I could harvest the dingleberries from my arse fur.
