A skidmark on the underpants of society

Someone who is so unpleasant to be around or even look at that he becomes no more than a turd to society. Not only that, he is a turd on society's Y-fronts. It would be benificial not only to society but to the Y-fronts of said society if said unpleasantries would kindly fuck off. Commonly used for thieves, homosexuals, and germans.

"Hitler, what a dick, I would go so far as to say he was a skidmark on the underpants of society."

"Get out of my boxers you fag! You're no more than a skidmark on the underpants of society!"

skidmark

A poo poo stain in your undies that is usually centralized, but not restricted to, the area that makes contact with the anus. Usually a sign that means you need to use toilet paper. WARNING: should you encounter skidmarked undies, dispose of them in short.

skidmarkalgia

A disorder characterized by brown streaks in the patient's underwear, usually in the rear. This condition is often misdiagnosed as skidmarks. The difference between them is that skidmarkalgia is typically wider spread and thinner, whereas skidmarks are more centrally located and darker. The exact causes are unknown, however anecdotal evidence suggests that fisting may be the primary cause skidmarkalgia.

“Maybe skidmarkalgia can be induced by fisting, FF, but not fibromyalgia.”-Village Voice

Skid marks

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.
