1.
Fecal matter on your finger following an errant wipe or toilet paper malfunction.

Sometimes when you're on the toilet, the wipe doesn't go as planned, when this happens you could end up with "Marl" on your finger.
Whenever I drop a duce in a gas station bathroom, the TP is so thin, I almost always end up with marl on my finger.
