Butt skin is an unfortunate situation but not at all uncommon.
Butt skin is where the skin on your face is absent of slight changes of color or pigment. Someone with Butt Skin will appear to have one monochromatic tone in their facial skin not unlike that on the buttocks. Butt skin can cover the entire body but is most noticeable on the face and neck areas.

When a person wipes their ass raw with toilet paper. Occurs usually when a person continuously travels to the bathroom in 10 minute intervals just to wipe their ass after a heavy meal.

Look for the person who goes to the bathroom often and looks like they have agony when sitting and taking brisk walks. Also possible suspect for using all the toilet paper in one's home.
Person 1: Who used all the toilet paper?

Person 2:Talk to your brother, he had Rumple Butt Skin.
