Combination of dingleberry and douchebag. Used to describe someone who is incredibly 1.) ignorant 2.) annoying 3.) stupid to the degree of deserving death by mutilation.
A dingle douche fucks up everything he touches and can do nothing correctly. Those around him wonder how he even knows to wipe his own anus hole after shitting.
Similar to a dingle berry, a dingle douche is when vaginal discharge is not wiped properly, resulting in dingle douches. A dingle douche can be used as a noun only. This word can be used to describe someone who is very annoying and/or disrespectful.
One day, a grandmother walked into my store, asking if we sold anything to help her with her pain near her vagina. I recommended her to buy something to treat her possible dingle douches.
