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.

Oh man, I really gotta take a crap!

Go in there!

I can't! There's no water in the toilet and someone already left a skidmark slam.

skidmark grand slam

N. The unusual situation of soiling three different pair of underpants in the same day.

What happened to Joey?

He had to go home. He hit a skidmark grand slam.

Man, that sucks.
