(stink-you-puss) n. A nauseatingly stinky vagina. It may also be covered in beastlike fur, which may be a defense mechanism for keeping flies or other vermin from feeding on it, mistaking it for some shit or rotting flesh. They also have been known to have ferocious fangs capable of severing a penis, tongue, finger, or any sort of object you can stuff in there. It can sense fear, so if you encounter one, turn around, run very quickly, and find a safe place to masturbate.
Person 1: "So, how was your date with my mom last night?"
Person 2: "Not good. Are you aware that your mom's tiger print granny panties house an unholy stinkupuss?"
Person 1: "Of course. Why do you think my face is grossly disfigured and makes everyone want to throw up?"
