cloacal
Shared excretory opening
Cloacal means relating to a cloaca—the single opening in birds, reptiles, amphibians, and some fish that serves as the exit for both digestive and reproductive systems.
The term appears in biology and veterinary contexts: cloacal vent, cloacal temperature.
Figuratively rare, but when used suggests something serving multiple unsavory purposes.
