Nocturnist 

A physician, usually one of the best in his or her feild, who is so adept at practicing medicine that they frequently handle any and all after hour emergencies in large hospitals with little to no help at bedside from colleagues or subspecialists. Usually high income earners with strong work ethic, very often referred to as the Guardian Angels of the hospital due to their ability to single handedly solve problems and keep critically ill patients alive at night. Can often teach Advanced Cardiac Life Support (ACLS) in their sleep. Often exclusively work at night. Proper noun, capitalization important differentiator from non-physician references.

"That physician is the best damn Nocturnist that I have ever had the privilege to work with... saved more lives at night than any other physcian I know."

Summer Nocturnality Syndrome 

Behavior often characterized in people with a summer break where the individual would start sleeping five o' clock in the morning and wake up two in the afternoon, because they simply and quite frankly don't give a damn.

Also known as Circadian Rhythm Sleep Disorder in the real world where people still don't really give a damn.

Step 1: Wake up
Step 2: Eat dinner
Step 3: Sleep

Repeat.

Mornings were made for sleep. I schedule all my studying, gaming, and partying between 11pm-3am. I'm a practicing nocturnist.
