look up any word, like smh:
(n) A relationship based purely on the physical aspects, with no romantic involvement that occurs after hooking up with the same person for a minimum of two to three times.
Jane: "I hooked up with John last night"
Alice: "That's the fourth time in the past two week! You're totally in a fornicationship"

Ryan: "Dude the whole relationship thing is bogus. All you need in life is a good fornicationship with some chick"
Freddie: "Now that would be ideal"
