shidmark 

the trail of fecal matter that remains on the circumference of a toilet bowl whereupon one's fecal mass lands during the act of defecation


usually as a result of bad gluteus positioning during defecation; causing excrement to drag upon the toilet bowl

the name derives from the combination of two words: shit + skidmark= shidmark

I felt bad leaving shidmarks on grandmas toilet, so i flushed several time to get rid of them.

A HUMAN SKIDMARK ON THE UNDERWEAR OF LIFE 

A contemptible and low-life individual;
a person who's a waste of oxygen and flesh; the ultimate scumbag of existence!

Pete's wife aptly labeled him as a "human skidmark on the underwear of life" when he forgot to acknowledge their 20th wedding anniversary by having an illicit fling with the baby-sitter at the local hotel.

Trailerpark Skidmark 

The Trailerpark Skidmark is a visible mark worn(usually about the neck)by a male or a female to ward off unwanted suitors of the opposite sex (much like the wearing of a ring in more popular cultures). The Trailerpark Skidmark is not your usual hickey by any means. This mark is worn and displayed proudly by the wearer, bragged upon by the issuer, and admired by others in their culture. True love in this cultere is observed when both parties in the relationship are wearing the coveted TrailerPark Skidmark.
You will find this culture displayed mainly in the great white ghettos of america(trailerparks, hence the name).
Approach those wearing the Trailerpark Skidmark with caution. The wearer usually:
1. Is drunk
2. On meth
3. Just got fired from their midnight shift at the local Huddle House
4. Stressed out because their period is late and not sure who the father could be
5. Upset because their Mustang GT or Iroc Z-28 just broke down...again
6. Is "good and fired up" because their baby sister just got knocked up by a black guy
7. Just got into a fist fight with their dad
8. Is the model for White Trash in American Society
9. Is a highschool drop out
10. And finally...JUST DOESN'T GIVE A FUCK

1. "Damn Jimbo...look at the shitter on that critter! I wonder if she's got a man?"
"You know she does JD, check out that Trailerpark Skidmark."

carbon skidmark 

1. The impact of carbon dioxide emissions, from an individual or a group, on air pollution and global warming.

2. A more accurate reflection of the impact of a carbon footprint. While a footprint leaves an impression, a skidmark leaves an indelible stain that is extremely undesirable and unpleasant.

Example #1: Jon got a brand new Escalade but that thing leaves a huge carbon skidmark.

Example #2: Some hippies were trying to convince me to give them money to offset my carbon skidmark so I told them to fuck off.

skidmark 

TV ad that stays onscreen during the entire program.

TV advertisers started with logo bugs, moved on to pharts and then graduated to skidmarks. Next, they'll move the program down to one corner of the screen and run continual ads over the remaining 90%.

Skidmarks 

Skidmarks are brown streaks left on the porcelain bowl of a toilet when someone takes a big firm dump that rubs the porcelain bowl swirling around until it orients itself for exit down the pipes.

Who left the skidmarks in the shitter!?!
