Toilet Paper Biscuit
The act of rolling toilet paper around one's hand several times to form a soft bisuit that an overweight person will place between folds of fat on their body (usually a roll of fat under the lower abdomen) to prevent chafing, absorb sweat, and to reduce skin irritations. At the end of the day, the person may chose to retire their biscuit, letting it air dry for re-use the next day, or save the biscuit to use to wipe their ass at a later date.
Cory made a new toilet paper biscuit each morning and placed it under the flap of his belly fat to absorb sweat so that his rash would heal. He kept his used toilet paper biscuits in his bathroom and later wiped his ass with them after taking a shit.
