The act of being sick at college (actually sick, not hangover sick), and spending all of your sick time on the futon, because you can't stay in bed any longer, but you're too sick to go any father than the couch.
"Kendell is really sick, her away message said she was on the futon... oh man, shes futoning!"
A type of relationship where one party is indisputably moored in the "friendzone." The result of that relationship inevitably leads to one party always sleeping on the futon, while the other gets the bed.
Friendzoner: "Hey, I'm feeling a little lonely, would you come over and watch a movie with me? You can sleep over if you like."
Friendzonee: "Really?!?"
Friendzoner: "Absolutely, but we have to keep it strictly futonic."
Friendzonee: "Ok, but can I cuddle with the cat tonight?"
Friendzoner: "For sure"
Futoni: a word you say instead of Fuck. It takes after the furniturepiece, the futon and she only be used in the rarest of circumstances, or when something is really messed up.
"Shut the futoni up about it"
"Futoni, I stubbed my toe"
"Gosh futoni darnittttttt"
When some resigns or retires from a job, they are on "eternity leave". This can also refer to someone who has passed away, especially someone who worked somewhere for a long time, retired/resigned, then passed away later.
Oh I'm sorry, you didn't know that Kelly is on eternity leave? She resigned and moved to Hawaii!
With regrets I would like to inform you that my boss is officially on eternity leave. I will never see or hear them again. Ever.
