Students' Sunday Night Syndrome is one of a student's most common anxieties. It's the feeling when you are sure you have no homework, but you are suspicious that you missed something or forgot an assignment. You feel free, but also a nagging anxiety that you're going to have to stay up late on the Sunday Night and work on it when you remember.

Students' Sunday Night Syndrome is often one of the symptoms of hardcore procrastinators.

Most of us with Sunday Night Syndrome react with sleeplessness or we just don't give a fuck and prepare for Monday Morning Homeroom Syndrome.
A: Yo man, why are you up so late
B: I have Students' Sunday Night Syndrome..I feel like I forgot an assignment

You are in your bed, it’s the last day of vacation before you go back to school... when you suddenly remember that you didn’t do your homework and you’re fucking screwed. That heart attack is the « holly shit Sunday night ». As you panick, you try to think about when and where you could, in less than one morning, finish all the homework that was given to you for the holidays.

The act of posting an angsty status or picture to Facebook complaining about the impending Monday. If you're lucky, you'll scroll past about five to ten of these.
Aw man, Sunday already? This seems like I can get away with a few likes by posting a Sunday Night Angst status.
