Dingle-Berry's Rejects are those that weren't lucky enough, and ended up small, alone, no hairs to dingle from. They are a nomad tribe, they originate on our crack, first they hang out with proper dingle-berries, eventually these two separate, the rejects fall from your crack to your underwear, there they can spend an undetermined amount of time depending on your personal cleaning habits, hours, days even weeks, but in most cases is short, from your underwear, to the bathroom and to the trash, the lucky ones may travel as far as your shoes or your mamma's kitchen floor.
They also suffer the pains of an unbalanced nature, some are more faeces than paper or vice-versa. Why does one dingle-berry is destined to a great journey and another to be rejected to the perils of a nomad life is still a mystery of nature. One can say they are different but none is better than the other, and to call them 'Rejects' is a matter of language and custom.
