buttcrusticles 

Buttcrusticles are the extended and frozen remnants of dingleberries, dinglebombs, buttsauce, or standard buttcrust. Buttcrusticles form in the greater crackal / ass regioning of the carrier during cold weather or during winter months. They often will return to their original form once heated or may fall off on their own in the form of a clinker.
They also can bang together forming butt chimes.

"Man it's so cold I have buttcrusticles banging like chimes in my ass!"

or

"I better go inside and warm up, my buttsauce has started forming buttcrusticles."
