Derogatory term for a furry.
This word originated in the late 1970s or early 1980s. Among the science fiction and fantasy fandoms of the time, furries were known for creating both visual and written pornography depicting animal characters (both humanoid and non-humanoid), and their favorite species to sexualize--those considered the most "sexy" to furries--included skunks and foxes.
A less popular deviation of this term with the same meaning is "foxfucker."
Those no-good skunkfuckers should throw away their fursuits, move out of their mothers' respective basements, and get jobs.
