1. Wiping and then fumbling with the used toilet paper before getting in the toilet, thus dropping it on the back of the seat near the tailbone.
2. Scooting off the toilet quickly in an attempt to get back to something quickly (i.e. TV, computer, etc.) or to pull one's own pants up after a bathroom intrusion as the result of an unlocked door, resulting in the sliding of a half-wiped anus on the front of the toilet seat.
