Uncontrollably falling into 10-20 minute sleeping spells at inappropriate times. Other symptoms include "the head bob", that can be seen as a student fights an on coming Napolepsy spell, and illegible or missing notes. Most often caused by monotonous drab professors and warm lecture halls.
"Dude bro Chad, can I get the notes from you later."
"Nah, sorry man, I had a hardcore Napolepsy attack."

"I caught a serious case of Napolepsy in ME107 with Lambropoulos this semester."
