Micro Derm Abrasion is what happens when you use cheap toilet paper - it makes your butt raw after repeated wiping much like sand paper would do.
Micro Derm Abrasions are common in office buildings, gas stations, Grandma's house, etc. In extreme cases there are chunks of wood embedded in the tissue.
Using the toilet paper in our office building is like getting a Micro Derm Abrasion on your butt.
Yet another term for going to the restroom, especially a public restroom with stalls.
So named because people tend to grunt, groan, and grumble while going poop, and the public restroom stalls are hut-like.
Well, I'm heading to grumble hut for a poo session. Seeya in about 30 minutes if all goes well.
