A person who insists on sleeping at a certain time each night and will even try to convince you to sleep early too. Cannot sleep with a computer monitor on and doesn't want you to work on your homework while he/she is sleeping even if you offer to position the monitor so as not to disturb him/her. Usually uptight about really minor stuff. Gets pissed off easily at night. Does not mind disrupting another person's education by making them work on homework the next day instead of finishing it at three in the morning while he/she is asleep.
That guy is such a sleep nazi. I had to use to the fucking computer lab the entire night because he was bitching about not getting to sleep at night.

Someone who won’t let you sleep. They are constantly making noise or doing something to wake you up so you can’t sleep
