Top definition
A penis so covered in hair that it cannot be stimulated to completion. The French Creole term for wolf dick. Shaving a gradeaux is a gra-don't, as it only turns it into something more sinister.
Girl: "Is your penis typically obscured by hair, or is there a full moon tonight?"
Guy: " Look out the window bitch, this gradeaux is here all month."
