A line or a spot of fecies left in one's underwear, either because they didn't wipe properly or they did not get all the poop out of their anus.

The combination of white underwear with a person with minimal butt wiping skills, or, someone, like Tom, who wears the same pair of undies for 3 days.
Tom wears his undies for 3 days without washing. He doesn't wipe very well and leaves nasty skid marks for his wife to try and get out with bleach and Sunlight bar soap. He's a dirty man.

A line of fecal matter in your underwear that varies in thickness from thin to meaty. Usually a result of poor asswiping skills.

Your skid marks and itchy butt don't just happen kids. You need to wipe better. Don't wipe your heiny with your underpants!
