/ ˈrætˌhoʊl / noun. "rathole" | plural "ratholes" 1) The largest orifice on a human skull, typically used for intake of food, or exchange of CO2 rich air, with oxygen rich air. Some humans try to communicate through their rathole, with varying degrees of success. It is called such, as it is the hole you eat rats with, therefore it is the rathole. Some deviants use their ratholes as a way to begin the mating ritual. Some in more perverse ways than others. The phrase was brought to common knowledge with the (alleged) fantasy time travel television/cable show, "Future Man" (2017, Hulu)
