A term that suggests that instead of sharing an abundant variety of fruits, a group should participate in sharing many sexual partners in an all out pile fuck.
It is typically used as a classy term when in public when it is unacceptable to refer to an orgy or a 'pile fuck'.
Chris: "Hey gang wanna have a pile fuck later!?"
Alex: "Dude we're at a restaurant, there's a kid right there! Be a little more discrete you barbaric animal."
Chris: "Oh I apologize my good sir. Hey you guys want to partake in a fornicornucopia later?"
A unicorn with a penis on its forehead instead of a horn. It can prod and poke with the same effectiveness as the unicorn. Ovbious to which gender this creature happens to be.
The penicorn frolicked gaily among the flowers...unbeknowest that poachers come in search of the rare sack it carried proudly on its forehead.
