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.

Joe's (Summer Nocturnality Syndrome Patient) Typical Day:

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

Repeat.
