Solid Fart 

The opposite of air dookie, a solid fart is just a poop...a dookie...a back door nib despencer. The use of this term when your dookie is a liquid is absolutely frowned upon.

I shit a brick and it was the worst solid fart I’ve ever experienced.

farting solids 

The act of taking an airy shit. Sounds like a continuous fart with intermittent plops. One of the most relieving shits, as usually the turds were blocking all the air from exiting the ass.

"Did you just take a shit in there?" "Sort of, but it was more like farting solids."
