The state of being awake long into the night and then being unable to wake up before noon. Similar to insomnia, inzomnia results in zombie like characteristics; smelly, intense fatigue, and overall uncleanliness.
Dude, why does that guy look like he has inzomnia, he probably doesn't sleep, like ever. But, when he does, it's probably until 4 p.m.
