Noun - The type of feces that occurs when a particularly hairy man's ass hairs bind after a hot day or sweaty workingout. Upon going to the washroom, it creates a grater-like effect when expelling fecal matter. The bound hairs proceed to shread the outgoing turds into spaghetti like strands, creating Shit Spaghetti. Particularly evident in Italian men.
"Dude, that hairy guy over there just dropped a load of shit spaghetti into the john
and forgot to flush."
