A fancy term for constantly having your head up your ass.

Used to describe certain groups of people who dial 911 for no reason with a BS medical complaint.
Patient: "Hello,911? Yes I think I'm having a stroke, I think I've had it for a month!"

EMT: "No sir, you have Hyper-rectalcranialitus. It's a pretty severe condition that you may need to get looked at. For removal of the cranium from rectum, it may require surgery."
