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.
An icicle formed under a portable loo. The shitwater seeps through the gaps in the portable loo and gather under the plastic. During winter, this freezes and therefore creates poopsicle.
