Fornication or adultery

Sticky Piston

When you use a piece of toilet paper you had just blown your nose in to wipe your ass, hoping the mucus would act as an adhesive and pick up any particles left behind. May also be used when low on toilet paper, but desperate. Named after the Minecraft object.

Barry was unfortunate enough to have both the cold and the flu at the same time, and when low on toilet paper, resorted to the Sticky Piston to kill two birds with one stone.
