Frozen ass gremlins, such as one may get while bar hopping on a cold night in Chicago. Cold/frozen poop particles that result from neglectful ass wiping.
A poop that literally freezes half way out the hole, so you have to use either your hands to pull it out, or even use an ice pick to break the ice stuck in your ass.
You know it's time to turn on the heat when you get a poopsicle.
