Quite literally. Human and other mammal scent receptors are very sensitive to thiols, sulfur compounds that are frequently found in sources of danger, like rotting corpses, feces, and toxic gas. Skunks evolved their spray to take advantage of this with high concentrations of thiols and compounds that help to adhere to things. It's like an olfactory flashbang.
