Smells like shit

Skatole, a digestion product of the amino acid tryptophan, is a major player in the smell of human feces. In low concentrations, skatole has a flowerly smell and is used in perfumes and other scent products. Perhaps unsurprisingly, skatole is a common flavor additive in cigarrettes. Its name is derived from the Greek root skato- meaning "dung."
