skidmark slam 

n. The rare art of dropping a deuce in a waterless toilet that leaves a skidmark the length and depth of the bowl.

Skidmark 

<noun>
1) Rubber that has been scorched into the road due to the heat caused by friction from someone's tyres when either they brake too hard or have accelerated too quickly from a stopping position and caused a 'burnout.'
2) Stains left on underwear due to poor anal hygiene which indeed resemble the tyre-marks scorched into the road.

1) "Whoa dude, look at that skidmark in the road! Someone must've had to brake to avoid that ominous pool of blood next to that body there."
2) MOTHER: "David, if I find another skidmark in your underpants when I come to wash them, I'm gonna come up there and wash your arse myself you little shit!"
