look up any word, like darude - sandstorm:
 
1.
The subtance you smoke when there is no pot available at all.
This material is derived from cleaning out the stem or pipe of a used bong.
The colour of Black shit is black and it smells like shit.
Black shit is only smoked in desperation.
"Hey, u got any pot man?"
"Nah bro only just got this"
"What the fuck is this smelly shit?"
"It's Black shit bro"
"Fuck smokin dat shit aye"
