As we humans finish up our doings in the restroom, we normally would wipe our area with a soft, comfortable tissue paper. When one forgets to perform this simple task of wiping, a single or several particles of feces get stuck to ones hair. This is sometimes called a dingleberry. Later on in the day when ones Swass moisturizes the dingleberry, the one with this issue will slowly get irritated to a point of no return. This emotional outburst is often called Crustfuss. Sometimes used in place of the word "PMS"
"FUCK you asshole im having a bad day!!"
"Dont worry, your just having a small case of Crustfuss."
