Fooliosis 

“Fooliosis” or the medical term “Fooliosis of the skull”. A word that describes temporary paralysis of the brain and motor functions. This state is usually induced by alcohol or other substances. Symptoms are obnoxious laughing and hallucinations. Fooliosis can lead to erratic and otherwise embarrassing behavior. The first case of fooliosis was reported in Telluride, Colorado circa June 2005.

"Leigh is acting very weird, she must have fooliosis."

"Mom and dad, I have fooliosis of the skull. Ha, ha!"

Doctor: "I'm sorry Timmy, but a person with a severe case of fooliosis, such as youself, has a maximum of 1 week to live."
