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.
Nickname given to bales of marijuana thrown overboard or out of airplanes. Origin is reportedly from members of the US Coast Guard in the area of Southern Florida.
"Base we've got some square groupers floating outside of Miami harbor."
